Title:
AUTOMOTIVE MOTOR, AND ELECTRIC POWER STEERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/097205
Kind Code:
A1
Abstract:
An embodiment of this automotive motor is an automotive motor mounted on a vehicle, wherein the automotive motor is provided with: a rotor having a shaft disposed along a center axis; a stator facing the rotor in the radial direction across a gap; and a circuit substrate disposed on one axial side of the stator and electrically connected to the stator. The stator has a stator core and a plurality of coils, each of the coils having a winding part formed by winding a coil wire around the stator core. At least one of the plurality of coils is a first coil having a first extension part formed by extending the coil wire from the winding part in one axial direction.
The first extension part has: a linking part joined to the winding part; and a fixed part fixed to the circuit substrate. The length of the first extension part from the linking part to the fixed part is greater than the length of an imaginary line segment connecting the linking part and the fixed part.
