Rotor and switched reluctance motor

A switched reluctance motor comprising:

• a rotor;
• and
• a stator, wherein
• the rotor includes:
• a rotor core rotatably disposed about a rotating shaft and formed of a first magnetic material;
• a plurality of first salient poles formed of the first magnetic material and formed on an outer peripheral surface of the rotor core at a predetermined first interval in a circumferential direction of the rotor core;
• a plurality of second salient poles provided radially outside the plurality of first salient poles of the rotor core and formed of a second magnetic material having lower iron loss than the first magnetic material;
• and
• a stopper, formed of an insulating material, that is engaged with the first salient poles and the second salient poles, and
• the stator includes:
• a stator core disposed on an outer diameter side of the rotor;
• and
• tooth portions that are formed on an inner peripheral surface of the stator core at a predetermined second interval in the circumferential direction of the stator core, each of the tooth portions having a coil of one phase among coils of a plurality of phases wound therearound.
