Benefits of technology

The present invention is a vacuum cleaner motor assembly that integrates a diffuser and a housing to simplify the structure and improve efficiency and reliability. The design features a stable support structure for the bearing part, which ensures better performance and operation of the motor.

Problems solved by technology

However, due to vibration or noise generated at the time of driving the switched reluctance motor (SRM) mounted in a vacuum cleaner module, operation performance of a product is deteriorated.
In addition, coupling force of two bearing parts coupled to upper and lower portions of a shaft are reduced, such that it is difficult to secure concentricity of the two bearing parts.
As a result, vibration and noise are generated due to the bearing parts at the time of an operation of the motor.

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.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of Korean Patent Application No. 10-2012-0091814, filed on Aug. 22, 2012, entitled “Switched Reluctance Motor Assembly”, which is hereby incorporated by reference in its entirety into this application.BACKGROUND OF THE INVENTION[0002]1. Technical Field[0003]The present invention relates to a switched reluctance motor assembly.[0004]2. Description of the Related Art[0005]Generally, a switched reluctance motor (SRM) called an SR motor is a motor in which both of a stator and a rotor have a magnetic structure, which is a salient pole, the stator has a concentrated type coil wound therearound, and the rotor is configured only of an iron core without any type of excitation device (a winding or a permanent magnet), such that a competitive cost is excellent.[0006]More specifically, the switched reluctance motor (SRM), which rotates a rotor using a reluctance torque according to a change in magnetic reluctance, ...
