Problems solved by technology

[0005] Although the switched reluctance motor is cheap due to the simple rotor structure, the switched reluctance motor has several problems: The switched reluctance motor uses a converter composed of semiconductor switches to generate reluctance torque, increasing the cost of the entire system , and for proper control in fast driving, it is necessary to include expensive control circuits capable of fast processing
[0009] As mentioned above, because the switched reluctance motor according to the prior art necessarily includes a converter for driving, a controller, and a position sensor, it may not be realized at low cost, due to the complicated technical structure, the switched reluctance motor in the design Motors have less degrees of freedom and have a higher probability of failure or error

Abstract

Disclosed herein is a switched reluctance motor including a rotor having a coil wound therearound; commutators connected to both ends of the rotor; brushes mechanically contacting the commutators by rotation of the rotor; and a stator having the brushes fixed thereto and having stator poles, wherein the brushes are moved by an advance angle from a connection axis of stator poles counterclockwise, and a dwell angle, a voltage application period is controlled by arc angles of the commutator and the brush.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to Korean Patent Application No. 10-2011-0002436, filed Jan. 10, 2011, entitled "Switched Reluctance Motor", the entire contents of which are hereby incorporated by reference in this application. technical field [0003] The invention relates to a switched reluctance motor. Background technique [0004] A general switched reluctance motor has a magnetic structure in which both the stator and the rotor are salient poles. In addition, the stator has coils wound intensively around the stator, and the rotor is formed of only an iron core without employing any exciting means such as windings, permanent magnets, etc. to have excellent price competitiveness. Further, the variable-speed switched reluctance motor can stably generate continuous torque by means of a converter using power semiconductor elements and position sensors, and can be easily controlled according to performance required f...
