Abstract
Disclosed is a switched reluctance motor which can reduce noise and prevent overheating in rotation of a rotor. The switched reluctance motor includes: a stator core having a plurality of inwardly protruded poles at predetermined intervals; coils wound around the protruded poles of the stator core; and a rotor core being rotatably housed inside the stator core with a predetermined gap, and having a plurality of outwardly protruded poles along the radial direction, and round units protruded from the front ends of each protruded pole of the rotor core starting to meet each protruded pole of the stator core, so that gaps between the protruded poles of the stator core and the protruded poles of the rotor core can be gradually reduced.

A switched reluctance motor, comprising:
- a stator core having a plurality of inwardly protruded poles at predetermined intervals;
- coils wound around the protruded poles of the stator core;
- and
- a rotor core being rotatably housed inside the stator core with a predetermined gap, and having a plurality of outwardly protruded poles along the radial direction, and round units protruded from the front ends of each protruded pole of the rotor core starting to meet each protruded pole of the stator core, so that gaps formed between the protrUded poles of the stator core and the protruded poles of the rotor core can be gradually reduced.
