Abstract:
1. A motor comprising: a rotor including a permanent magnet type rotor unit having a plurality of permanent magnets and a reluctance type rotor unit having a plurality of salient pole portions, said rotor units being coupled to each other in an axial direction; and a stator that generates a field for driving said rotor, said permanent magnet type rotor unit and said reluctance type rotor unit having an angular deviation δ therebetween in a direction of rotation, said angular deviation δ corresponding to a mechanical angular equivalent of a difference θ between a current phase value θ said reluctance type rotor unit having slits that prevent flux leakage from said permanent magnets, said slits being provided at said angular deviation δ in the direction of rotation from respective positions symmetric about a center of said salient pole portions.
