"Double-fighting hegemony", the love of passenger car motor
After reading the above, we have a general understanding of the market distribution of these three genres. In the passenger vehicle field, permanent magnet synchronous motors and AC asynchronous motors are mainly used, and passenger cars are more closely connected with our daily life, so we It is necessary to talk about these two genres separately.
Friends who are more concerned about new energy vehicles may have a perception that most domestic OEMs prefer to use permanent magnet synchronous motors, while European and American countries prefer to use AC asynchronous motors. New energy vehicles such as the domestic BYD Qin ProEV500, the new generation Song EV500, the Geely Dorsett EV, and the Roewe ERX5 are equipped with permanent magnet synchronous motors. Foreign OEMs such as Tesla, ModelS and ModelX use AC asynchronous motors, but there are exceptions. Domestically, Weilai and Jiangling are also equipped with AC asynchronous motors, but few of them are well-known manufacturers. I can see the model that uses AC asynchronous motor.
Although the current market share of permanent magnet synchronous motors is larger, there have been some times when AC asynchronous motors have been widely used in the market because of their strong overload capability, better acceleration performance and more stable structure. Synchronous motors can go against the trend? The main reason is that AC asynchronous motors have high energy consumption, large heat, heavy weight, and need large volume cooling system. These shortcomings directly cause the "AC asynchronous professional households" like Tesla to constantly enlarge the body. Increase energy density to ensure endurance. It can be said that the disadvantages in terms of energy consumption weight and volume firmly limit the development of AC asynchronous motors in the field of passenger cars.
