Motor

A motor comprising:

• a stator including a plurality of armature pole coils for generation of magnetic flux when energized,
• a rotor mounted for rotation within the stator owing to the magnetic flux,
• the rotor being formed with a plurality of main salient structures, which are directed toward the stator and distant one after another in a predetermined direction, and a plurality of auxiliary salient structures, which are directed toward the stator and distant one after another in the predetermined direction in a way that each of the plurality of auxiliary salient structures is situated between the adjacent two of the plurality of main salient structures,
• the plurality of main and auxiliary salient structures including induction coils, each for generation of induced current when linked by space harmonics contained in the magnetic flux, and electromagnetic coils, each for generation of electromagnetic force when energized by the induced current generated by the induction coil.
