Technological Trends in Motor Development

Overall, permanent magnet synchronous motors have significant advantages over induction motors. However, the current range of pure electric vehicles is bound to be an extremely important indicator, and the high efficiency of permanent magnet synchronous motors can better improve the range. Moreover, the successful development of high heat resistance and high magnetic performance neodymium iron boron permanent magnets, as well as the further development and improvement of power electronic components, have further improved the development of rare earth permanent magnet synchronous motors. But looking at the current development trend, permanent magnet synchronous motors seem to have better prospects.

With the rapid development of new energy vehicle driving technology, many new structures or concepts of motors have been put into research. The new type of permanent magnet brushless motor is currently one of the promising motors, including hybrid excitation type, hub type, double stator type, memory type, and magnetic gear composite type. In addition, amorphous motors have also begun to enter the field of new energy vehicles. As a new generation of high-performance motors, their own advantages will undoubtedly play a huge role in promoting the development of the new energy vehicle industry.
