Abstract
A synchronous reluctance motor includes a rotor having a rotor iron core and a stator having pole teeth. The rotor iron core defines multiple magnetic poles. A magnetic barrier area is defined between adjacent magnetic poles in a circumferential direction, and a conductor area is located at a radially outer side of the magnetic barrier area. The magnetic barrier area is provided with a hole arranged in multiple layers in a radial direction and defining a magnetic barrier. The conductor area is provided with multiple conductors arranged at substantially equal intervals in the circumferential direction and having substantially identical cross-sectional shapes as each other. The following relationship is satisfied: Nc={2×[Nt/(2×Np)−1]−1}×Np where Nt is a number of the pole teeth, Np is a number of the magnetic poles, and Nc is a number of the conductors.
