Mobil listrik masih dibayangi oleh perkembangan bateraiPerkembangan pesat powertrains hybrid dan kemajuan yang belum pernah terjadi sebelumnya dalam beberapa tahun terakhir di bidang kendaraan listrik adalah fokus utama pengembangan teknologi baterai. Mereka membutuhkan sumber daya maksimum dari pengembang dan merupakan tantangan terbesar bagi para desainer. Namun, orang tidak boleh meremehkan fakta bahwa kemajuan dalam pengembangan teknologi lithium-ion yang canggih disertai dengan kemajuan yang signifikan di bidang pengaturan tenaga arus listrik dan motor listrik. Ternyata meski motor listrik memiliki efisiensi yang tinggi, namun memiliki bidang yang serius untuk berharap industri ini tumbuh pada tingkat yang sangat tinggi, tidak hanya karena kendaraan listrik menjadi lebih umum, tetapi juga karena elektrifikasi kendaraan bertenaga pembakaran merupakan elemen penting dari tingkat emisi yang ditetapkan di Uni motor listrik memiliki sejarah kuno, para desainer saat ini menghadapi tantangan baru. Motor listrik, tergantung tujuannya, dapat memiliki desain yang sempit dan diameter yang besar atau diameter yang kecil dan tubuh yang panjang. Perilaku mereka dalam kendaraan listrik murni berbeda dengan kendaraan hibrida, di mana panas yang dihasilkan oleh mesin pembakaran internal harus diperhitungkan. Untuk kendaraan listrik, rentang kecepatannya lebih lebar, dan yang dipasang pada sistem hybrid paralel pada transmisi harus dioptimalkan untuk beroperasi dalam rentang kecepatan mesin bakar. Sebagian besar mesin bekerja dengan tegangan tinggi, tetapi mesin listrik 48 volt akan menjadi semakin motor ACTerlepas dari kenyataan bahwa sumber listrik dalam baterai adalah arus searah, perancang sistem kelistrikan saat ini tidak berpikir untuk menggunakan motor listrik DC. Bahkan dengan kerugian konversi, unit AC, terutama unit sinkron, mengungguli unit DC. Tapi apa sebenarnya arti motor sinkron atau asinkron? Kami akan memperkenalkan Anda ke bagian dunia otomotif ini, karena meskipun mobil listrik telah lama ada di mobil dalam bentuk starter dan alternator, teknologi yang benar-benar baru telah diperkenalkan di bidang GM dan BMW sekarang adalah beberapa dari sedikit produsen yang telah mengambil alih pengembangan dan produksi motor listrik itu sendiri. Bahkan anak perusahaan Toyota, Lexus, memasok perangkat tersebut ke perusahaan lain, Aisin Jepang. Sebagian besar perusahaan mengandalkan pemasok seperti ZF Sachs, Siemens, Bosch, Zytec atau perusahaan Cina. Jelas, pesatnya perkembangan bisnis ini memungkinkan perusahaan tersebut untuk mendapatkan keuntungan dari kemitraan dengan produsen mobil. Sedangkan dari sisi teknologi, dewasa ini untuk kebutuhan kendaraan listrik dan hybrid lebih banyak digunakan motor sinkron AC dengan rotor luar atau untuk secara efisien mengubah baterai DC menjadi AC tiga fase dan sebaliknya sebagian besar disebabkan oleh kemajuan teknologi kontrol. Namun, tingkat arus dalam elektronika daya mencapai tingkat yang berkali-kali lipat lebih tinggi daripada yang ditemukan di jaringan listrik rumah tangga, dan seringkali melebihi 150 ampere. Ini menghasilkan banyak panas yang harus ditangani oleh elektronika daya. Saat ini, volume alat kendali elektronik masih besar karena alat kendali semikonduktor elektronik tidak bisa dikurangi dengan tongkat sinkron dan asinkron adalah jenis mesin listrik medan magnet berputar yang memiliki kerapatan daya lebih tinggi. Secara umum, rotor motor induksi terdiri dari paket sederhana lembaran padat dengan belitan hubung singkat. Arus mengalir dalam belitan stator dalam pasangan yang berlawanan, dengan arus dari salah satu dari tiga fasa mengalir dalam setiap pasangan. Karena masing-masing dari mereka digeser dalam fase 120 derajat relatif terhadap yang lain, diperoleh apa yang disebut medan magnet berputar. Ini, pada gilirannya, menginduksi medan magnet di rotor, dan interaksi antara dua medan magnet - berputar di stator dan medan magnet rotor, mengarah ke entrainment rotasi terakhir dan selanjutnya. Namun pada motor listrik jenis ini, rotor selalu tertinggal dari medan karena jika tidak ada gerak relatif antara medan dan rotor maka tidak akan menimbulkan medan magnet pada rotor. Dengan demikian, tingkat kecepatan maksimum ditentukan oleh frekuensi arus suplai dan beban. Namun, karena efisiensi motor sinkron yang lebih tinggi, sebagian besar pabrikan tetap sinkronUnit ini memiliki efisiensi dan kepadatan daya yang jauh lebih tinggi. Perbedaan yang signifikan dari motor induksi adalah bahwa medan magnet pada rotor tidak diciptakan oleh interaksi dengan stator, tetapi merupakan hasil dari arus yang mengalir melalui belitan tambahan yang dipasang di dalamnya, atau magnet permanen. Jadi, medan di rotor dan medan di stator adalah sinkron, dan kecepatan motor maksimum juga bergantung pada putaran medan, masing-masing, pada frekuensi arus dan beban. Untuk menghindari kebutuhan catu daya tambahan ke belitan, yang meningkatkan konsumsi daya dan memperumit regulasi saat ini pada kendaraan listrik modern dan model hibrida, motor listrik dengan apa yang disebut eksitasi konstan digunakan, mis. dengan magnet permanen. Seperti yang telah disebutkan, hampir semua pabrikan mobil semacam itu saat ini menggunakan unit jenis ini, oleh karena itu, menurut banyak ahli, masih ada masalah dengan kekurangan unsur tanah jarang yang mahal yaitu neodymium dan disprosium. Motor sinkron hadir dalam berbagai variasi dan solusi teknologi campuran seperti BMW atau GM, tetapi kami akan memberi tahu Anda lebih banyak kendaraan listrik murni biasanya digabungkan langsung ke diferensial poros penggerak dan daya ditransfer ke roda melalui poros poros, mengurangi kehilangan transmisi mekanis. Dengan tata letak di bawah lantai ini, pusat gravitasi berkurang dan keseluruhan desain balok menjadi lebih kompak. Situasinya sangat berbeda dengan tata letak model hybrid. Untuk hibrida penuh seperti mode tunggal Toyota dan Lexus dan mode ganda Chevrolet Tahoe, motor listrik dihubungkan dengan beberapa cara ke roda gigi planet di drivetrain hibrida, dalam hal ini kekompakan membutuhkan desainnya yang lebih panjang dan lebih kecil. diameter. Dalam hibrida paralel klasik, persyaratan kompak berarti bahwa perakitan yang pas antara flywheel dan gearbox memiliki diameter lebih besar dan cukup datar, dengan pabrikan seperti Bosch dan ZF Sachs bahkan mengandalkan desain rotor berbentuk cakram. Ada juga variasi rotor - jika pada Lexus LS 600h elemen putar terletak di dalam, pada beberapa model Mercedes rotor putar berada di luar. Desain terakhir juga sangat nyaman jika motor listrik dipasang di hub Georgy Kolev Motor drives are a ubiquitous technology for transforming the constant voltage from the main ac power supply into a voltage that varies to control motor torque and speed ideal for motors that are driving mechanical equipment loads. Motor drives provide higher efficiency than simple online motors and a degree of control not available on simple directly driven motors. These factors result in energy cost saving, higher production performance and extend the life of the motor. According to the Department of Energy DOE, motor systems are critical to the operation of almost every plant, accounting for 60% to 70% of all electricity used. The DOE also identifies variable frequency drives VFD as a source to provide plants with significant cost savings. Not surprisingly, motor drives are commonly used in many industries and facilities. To ensure uptime in these motor systems, maintenance and troubleshooting is a to testing motor drivesTroubleshooting and testing motor drives, also known as variable frequency drives VFD, variable speed drives VSD or adjustable speed drives ASD, is often performed by specialists using several test instruments, including oscilloscopes, digital multimeters or other test tools. Such testing can involve a degree of trial and error, using the age-old process of elimination. Due to the complexity of the motor systems, testing often occurs annually unless a system begins to fail. Determining where to begin testing can be problematic considering there is usually a lack of, or incomplete, work history for the equipment. This includes documentation of specific tests and measurements performed previously, work completed or the as-left condition of individual components. Advances in testing technology have eliminated some of the challenges. Newer instruments, such as the Fluke Motor Drive Analyzers are designed to make motor drive testing more efficient and insightful with of the capability to document the process at each step along the way. These reports can be stored and compared against subsequent tests to get a bigger picture of motor drive maintenance easier way to troubleshoot VFDsCombining the functions of a meter, handheld oscilloscope and recorder with the guidance of a skilled instructor, these advanced motor drive analyzers employ on-screen prompts, clear setup diagrams, and step-by-step instructions written by motor drive experts to guide you through the essential tests. This new method to break down and simplify complex testing enables an experienced motor drive specialist to work quickly and with confidence to get the detail they demand. It also provides a quicker path for less experienced technicians to start motor drive to the root cause of a motor drive system failure or performing a routine preventive maintenance check is best done with a set of standard tests and measurements at key points within the system. Beginning with the power input, key tests with different measurement techniques and evaluation criteria are completed throughout the system, ending at the are essential tests for troubleshooting motor drivesNote that the Fluke Motor Drive Analyzers guide you through these tests and automate many of the needed calculations so you can have confidence in the results. Plus, you can save data to a report at nearly any testing point so you can have documentation to upload to a computerized maintenance management system CMMS or share with a colleague or consulting note Remember to always read product safety information before you begin testing. Do not work alone, and comply with local and national safety codes. Use personal protective equipment approved rubber gloves, face protection, and flame-resistant clothes to prevent shock and arc blast injury where hazardous live conductors are begin each test with a Fluke Motor Drive Analyzer simply connect the test probes according to the diagram, then press Next. Drive input step-by-step guided measurement connections 1. Drive InputAnalyzing the power going into the motor drive is an excellent first step to determine if a feeder circuit to the drive has distortion, disturbance or noise that may be affecting power the drive’s nominal rated voltage to the actual supplied voltage to quickly see whether values are within acceptable limits. More than 10% out of range could indicate a supply voltage problem. Determine if the input current is within the maximum rating and the conductors are suitably measured frequency against specified frequency. More than difference could cause whether the harmonic distortion is within an acceptable level. Visually inspect the waveform shape, or view the harmonics spectrum screen which shows both the total harmonic distortion and individual harmonics. Flat-top waveforms, for example, can indicate a nonlinear load connected to the same feeder circuit. If Total Harmonic Distortion THD is over 6% there is a potential the voltage unbalance at the input terminals to ensure the phase unbalance is not too high less than 6 to 8% and that the phase rotation is correct. High voltage unbalance reading can indicate phase failure. A reading over 2% can lead to voltage notching and cause a trip of the drive’s overload fault protection or disturb other for current unbalance. Excessive unbalance may indicate a drive rectifier problem. A current unbalance reading of over 6% could point to a problem within the inverter of the motor drive and be DC BusThe conversion of AC to DC inside the drive is critical. Having the correct voltage and adequate smoothing with low ripple is required for the best drive performance. High ripple voltage may be an indicator of failed capacitors or incorrect sizing of the connected motor. The record function of a Fluke MDA-500 Series Motor Drive Analyzer can be used to check DC bus performance dynamically in the operating mode while a load is applied. Alternately, a Fluke ScopeMeter Test Tool or advanced multimeter can be used for this Ripple on a DC Bus Determine if the DC bus voltage is proportional to the peak of the input line voltage. Except for controlled rectifiers, the voltage should be about to times the RMS line voltage. A low DC voltage reading can trip the drive, which can be caused by low input mains voltage or input voltage distortion such as flat for any distortion or error in peak amplitude of the line voltage. This can cause an over- or under-voltage error. A DC voltage reading +/- 10% from the nominal voltage can indicate a if the peaks of the AC ripple have a different repetition level. After the AC-to-DC conversion, a slight AC ripple component will remain on the DC bus. Ripple voltages above 40V can be caused by malfunctioning capacitors or a drive rating too small for the connected motor or load. Voltage and current on the drive output 3. Drive OutputTesting the drive output is critical to proper motor operation and can offer clues to problems within the drive if the voltage and current are within limits. High output current may make the current run hot, decreasing stator insulation the voltage/frequency ratio V/Hz to ensure it is in specified limits of the motor. A high ratio may make the motor overheat; a low ratio will make the motor lose torque. Stable frequency and unstable voltage can point to a DC bus problem; unstable frequency and stable voltage can indicate switching IGBT problems. Unstable frequency and voltage indicate potential issues with the speed control the output of the drive focusing both on voltage to frequency ratio V/F, and voltage modulation. When high V/F ratio measurements are experienced, the motor may overheat. With low V/F ratios, the connected motor may not be able to provide the required torque at the load to sufficiently run the intended for voltage modulation using phase-to-phase measurements. High voltage peaks can damage motor winding insulation and cause the drive to trip. Voltage peaks higher than 50% nominal voltage are the steepness of the switching impulses indicated by the drive reading. The rise time or steepness of impulses are indicated by the dV/dt reading rate of voltage change over time and should be compared to the motor’s specified the switching frequency with phase to DC. Identify whether there is a potential issue with electronic switching or grounding, which may be indicated when the signal floats up and voltage unbalance, preferably at full load. The unbalance should not be more than 2%. Voltage unbalance causes current unbalance, which can result in excessive heat in motor winding. Causes for unbalance can include faulty drive circuits. If a phase shows a failure it is called “single phasing,” which can make a motor run hot, not start after stopping, lose significant efficiency and potentially damage the motor and the connected current unbalance, which should not exceed 10% for three phase motors. Large unbalance while voltage is low can point to shorted motor windings or phases shorted to ground. Large unbalance can also cause drive tripping, high motor temperatures and burnt windings4. Motor InputVoltage supplied at the motor input terminals is key, and cable selection from drive to motor is critical. Incorrect cabling selection can result in both drive and motor damage due to excessive reflected voltage peaks. These tests are mostly identical to those for drive output that the current present at the terminals is within the motor rating. Over current conditions can cause the motor to run hot and decrease the life of the stator insulation which can result in the early failure of the modulation helps identify high voltage peaks to ground that could damage the motor unbalance that can seriously affect the life of the motor and may be an indication of a faulty inverter. This can lead to voltage notching and cause tripping the overload fault unbalance can point to voltage unbalance or drive rectifier problems. 5. Motor Shaft VoltageVoltage pulses from a motor drive can couple from a motor’s stator to its rotor, causing a voltage to appear on the rotor shaft. When this rotor shaft voltage exceeds the insulating capacity of the bearing grease, flashover currents sparking can occur, causing pitting and fluting of the motor bearing race, damage that can cause a motor to fail the voltage between the motor chassis and the drive shaft. The MDA-550, for instance, provides a carbon fiber brush probe for this purpose. The test can easily detect the presence of destructive flashover currents, while the impulse amplitude and count of events will enable you to take action before failure occurs.
