[Objective] With the increasing depletion of non-renewable resources and the worsening environmental pollution

new energy vehicles have become an important development direction in the automotive industry. Drive motors are the key components that determine the performance of new energy vehicles. [Methods] This paper provides an overview of the current status of drive motor technology for new energy vehicles

introduces the new hybrid excitation technology and its application in drive motors for new energy vehicles

and offers a prospect for the future development of this technology. [Results] First

four existing types of drive motors for new energy vehicles-DC motor

AC asynchronous motor

switched reluctance motor and permanent magnet synchronous motor-were introduced. Based on an analysis of the advantages and disadvantages of the existing drive motors

the hybrid excitation motor

which offers higher performance and compatibility with new energy vehicles

was introduced. Second

the driving principle of the hybrid excitation motor was explained. This motor features both permanent magnet excitation and electromagnetic excitation as two magnetic flux sources

which jointly control and regulate the motor’s air-gap magnetic field. It has advantages such as diverse structural forms

high power density

and a wide speed range

making it highly valuable in fields like wide-range magnetic field regulation for drive motors of new energy vehicles. Third

from the perspective of permanent magnet placement

the two different structures of hybrid excitation motors-rotor permanent magnet type and stator permanent magnet type were discussed in detail. Based on this

the control strategies for hybrid excitation technology were summarized

and its application in new energy vehicles was briefly described. Finally

the future development trends of drive motors for new energy vehicles were analyzed and prospected. [Conclusion] Based on the analysis of the advantages and disadvantages of the four commonly used motors for new energy vehicles and the current status of hybrid excitation technology

it is concluded that hybrid excitation technology has strong application prospects in the field of drive motors for new energy vehicles.
