Abstract
The present invention relates to a motor for electric power steering.
Motor for electric power steering according to an embodiment includes a housing; A bracket coupled to an upper portion of the housing; A stator and a rotor disposed in the housing; A rotating shaft coupled to the rotor; A sensing plate coupled to the rotating shaft and having guide protrusions protruding on an outer circumferential surface thereof; A sensing magnet installed on the sensing plate and in contact with the guide protrusion; And a sensing element facing the sensing magnet.
Description
The present invention relates to a motor for electric power steering.
The vehicle is provided with an ECU (Electric Control Unit) for receiving electrical signals detected by various input sensors and outputting digital control signals for driving various actuators on the output side.
In addition, the motor for electric power steering assists the driver's steering force to receive a signal from the ECU so that the driver can steer lightly and quickly.
An embodiment provides a motor for electric power steering.
Embodiments provide a motor for electric power steering in which a sensing magnet can be placed in the correct position.
