Abstract
The present invention relates to a layout and a drive method of an in-wheel motor used for driving a vehicle. In a vehicle using a direct drive in-wheel motor, there is a problem that mechanical loss is caused by a load on an axle due to a weight of a vehicle body, a direction change during traveling, and the like. A stator of the direct drive in-wheel motor is eccentrically disposed in a half peripheral part on the front side of the vehicle body. A terminal of a stator that generates a rotational torque reaction conflicting with a load applied to an axle during traveling is preferentially activated. A mechanical loss of a direct drive in-wheel motor due to a load on an axle during traveling of a vehicle is reduced.
Claims1
A drive method of an in-wheel motor in an electric vehicle using a direct drive in-wheel motor, the drive method comprising:
- preferentially activating a terminal of a stator that generates a rotational torque reaction conflicting with a load that is caused by a weight of a vehicle body and a direction change of the electric vehicle and that is applied to an axle during traveling.
