Title:
MOTOR FOR ELECTRIC VEHICLE
Document Type and Number:
Japanese Patent JPH05292703
Kind Code:
A
Abstract:
PURPOSE: To miniaturize a motor system and reduce radio noises while efficiently conducting cooling.
CONSTITUTION: A motor body 22 and a controller 24 are unified through a heat sink 26. Wirings from the controller 24 to the motor body 22 are shortened, thus saving space, then reducing radio noises. A coolant is flowed into the heat sink 26 and the controller 24 is cooled, and the motor body 22 is supplied with the coolant after flowing to cool the motor body 22. Circuits in the controller 24 are arranged in an axial symmetric manner. The deviation of heat generation is prevented by equalizing the distribution of heat sources, thus improving cooling efficiency.
