Title:
IN-WHEEL MOTOR DEVICE AND IN-WHEEL MOTOR CONTROLLER THEREFOR
Document Type and Number:
Japanese Patent JP2016092995
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an in-wheel motor device that can omit electric wires through which motor currents of respective phases flow from a controller to a motor coil, make a driving and control system, including the in-wheel motor device and a controller therefor compact, lightweight, and low-cost on the whole, suppress radiation of noise, and facilitate heat radiation of the controller.SOLUTION: An in-wheel motor device 5 is mounted with motor current control means 10. The motor current control means 10 has a switching circuit 24, consisting of an H bridge circuit of three phases or more composed of a plurality of switching elements, therein, and changes electric connections of coils of the motor 25 to control a driving current of the motor 25. The motor current control means 10 has a PWM modulation part 23 therein, and generates a PWM wave from phase current command values of three phases or more so as to control the switching circuit 24.SELECTED DRAWING: Figure 2
