Title:
VEHICLE DRIVE SYSTEM AND VEHICLE COMPRISING IT
Document Type and Number:
WIPO Patent Application WO/2006/054676
Kind Code:
A1
Abstract:
A rotary electric machine (1) comprises a stator (2) and a rotor (3). A tip end at the salient pole section of the rotor (3) is cut off asymmetrically in the lateral direction. Consequently, torque ripple is reduced during regenerative operation. Countermeasure against torque ripple is taken by the structure of the rotary electric machine for regenerative operation which is not carried out during low speed traveling but frequently carried out during high speed traveling because the driver is more sensitive to noise than during powering operation. For powering operation where the driver is sensitive to noise during extremely low speed traveling, it is preferable to take countermeasure against torque ripple by supplying a compensation current from a controller. It is possible to provide a small and high output vehicle drive system in which torque ripple is reduced and a vehicle comprising that system.
