Title:
IN-WHEEL MOTOR SYSTEM AND ELECTRIC AUTOMOBILE
Document Type and Number:
WIPO Patent Application WO/2019/004062
Kind Code:
A1
Abstract:
Provided is an in-wheel motor system with which the amount of wiring between an in-wheel motor drive device and an inverter device can be reduced, and a situation in which the in-wheel motor drive device is large and thus difficult to be put into the wheel can be eliminated. In a system in which an in-wheel motor drive device (10) and an inverter device (1) mounted on a vehicle body are connected by wiring, the following are installed in the in-wheel motor drive device (10): an RD converter (2) that converts a detection signal of a resolver (6), which detects the rotation of a motor, to a digital signal; a temperature sensor circuit (18) that processes a detection signal of a motor temperature sensor (11); and a communication circuit (22). A superposing means (28) that superposes a signal on the power source current may be provided.
