摘要

A traction electric drive for an electric automobile (EA) using a rectifier electric drive (RED) is being developed due to the number of advantages which it has over other types of electric drives. The possibility for designing a compact engine reveals the promise for developing a motor-wheel of a multimotor modification which will make it possible to improve the flexibility of the control and the reliability of the drive of an electric automobile. The basic technical requirements determined by the specifics of designing and developing a motor are: high ratios of torque when accelerating and climbing, high efficiency in a wide rpm range and limited weight and size with minimal possibilities for cooling and rigid operating conditions. The use of high-energy permanent magnets made of rare-earth elements has made it possible to develop a motor which provides the required operating modes and performance at the required size. The design of a developed motor is discussed. (ERA citation 05:036882)
