Basic knowledge of comprehensive interpretation of the electric car motor

Source: 2020 - 03 - 28 15:20 hits: once a comprehensive understanding of basic knowledge of electric motor of electric cars faster and faster now opened, and the development of the electric motor, has caught our attention, but few really understand the electric motor. The author has collected a lot of information for us, for us to talk about the electric motor. Let's get together to discuss high-tech car heart! A comprehensive understanding of basic knowledge of electric motor electric car motor position of the brain's electrical control system, electric cars, electric cars, electronic commands, and on-board power generation system, electric control system of the core technology, it is connected to the battery and battery pack and bond system, including battery processing skills, car charging technology and the bus DCDC skills and motivation system, and so on. Therefore, vehicle dynamic systems skills became a important direction of research on industrial application skills, also has increasingly become the important symbol of industry open. At present, this technology has become an important bottleneck electric car industry chain link and open. Industry transformation of the electric car electric car motor show traces of the conversion from development to industrialization, major automobile enterprises and power battery, the central part of the drive motor, controller and other production enterprises in the years to promote the pilot work, expand open, launched a series of satisfying the functional requirements of the product. But as the drive motor of the common key technology, its key components technology such as battery, its main indexes such as reliability, funds, durability still cannot meet the requirements of electric car open, become the main constraint factors of electric cars to open. The development of the electric motor is a problem from the point of the electric car industry chain, profit is likely to be concentrated in the central, the upstream resources in the control of the company has a strong resources will benefit more. The main cause of the development difficulties as follows: the first of the list is: battery electric vehicle technology and funds was the biggest bottleneck. Second: as a result of the mineral resources scarcity, lithium, nickel and other upstream resources will have a larger profit. Third: now the vehicle manufacturer is scattered, no determine the advantage of exclusive first, the first thing to note is likely to have core skills may have sophisticated skills, commercial vehicle manufacturers. Electric car motor drive system for high voltage, small quality, large starting torque, speed regulation planning, excellent starting and accelerating functions, high power, low loss, high reliability. When choosing the electric car motor drive system, the need to consider several key questions: cost, reliability, power, protection, scale, weight and durability, and noise. In pure electric car motor selection, including the choice of type, power, torque and speed.
