Patent Images
1. A switched reluctance motor assembly comprising:
- a shaft forming the center of rotation of a motor;
a rotor part rotatably coupled to the shaft;
a first stopper coupled to an upper portion of the rotor part in an axial direction to support the rotor part;
a second stopper coupled to a lower portion of the rotor part in the axial direction to support the rotor part;
a first bearing part coupled to an upper portion of the first stopper in the axial direction;
a second bearing part coupled to a lower portion of the second stopper in the axial direction;
a diffuser part supporting the first bearing part and coupled to an upper end of the first stopper; and
a motor housing formed integrally with the diffuser part and receiving the first and second bearing parts therein.

Abstract
Disclosed herein is a switched reluctance motor assembly capable of reducing an assembling error that is generated according to separate assembling and improving precision of assembling of bearing parts by forming a diffuser part and a motor housing integrally with each other. In the switched reluctance motor assembly, the diffuser is coupled integrally with the housing, such that a separate member for fixing the diffuser is omitted, thereby making it possible to reduce vibration according to driving of a motor and noise according to the vibration.
