Abstract

Disclosed is an EPS motor, the EPS motor including a motor housing mounted with a stator and a rotor, a rotation shaft centrally mounted at the motor housing to rotatably support the rotor, a bearing including an outer race centrally fixed at the motor housing and an inner race having a pivot hole rotatably fixing the rotation shaft, and a shaft fixing unit formed by plastically deforming a distal end of the rotation shaft having passed the pivot hole.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority from Korean Application No. 10-2011-0076007 filed on July 29, 2011, the entire contents of which are hereby incorporated by reference. technical field [0003] The present disclosure relates to an EPS motor. Background technique [0004] In general, almost every vehicle uses electric power steering. This electric power steering system generates power assist based on steering torque and steering angle, thereby improving the steering performance of the vehicle. [0005] That is, a steering system that assists a steering force of a vehicle using a separate power is used to improve the motion stability of the vehicle. [0006] Traditionally, hydraulic pressure has been used in auxiliary steering devices, but from the viewpoint of reducing engine load, reducing weight, improving steering stability, and quick return force, recently, the use of a motor suitable for transmitti...
