Abstract

Recently, electric vehicle motors arc mainly synchronous motor or induction motor, which arc high-speed and high-powered combined with a reduction gear because of size and weight point of view. By the advancement of magnet materials, electromagnetic steel sheets, winding technology, and control technology the 1PM method of synchronous motor has been researched for electric vehicle use. However, they are also high-speed, high-powered motors, which are combined with a reduction gear. In the year 2004, Keio University Electric Vehicle Laboratory has developed a high performance electric vehicle called; "'Eliica" Eliica's performance exceeded that of existing internal combustion vehicles and reached a maximum speed of 370km/h, an acceleration of 0-100km/h in 4 seconds. However, for driving range, there is still more room for improvement. At Keio University Electric Vehicle Laboratory a direct drive motor; which does not use any reduction gear and directly transmit the output to the wheel from the motor axis has been experimentally manufactured. This direct drive motor is an IPMSM that has an outer rotor structure. In this paper, comparisons between direct drive motor, which is low speed high torque, and high-speed high-powered inner rotor motor is done to see which motor is better for the use of electrical vehicles. From these experiment results, by mounting this motor in Eliica, the driving range is estimated to be 1.3 times longer.
