Abstract
A motor having a rotor and a stator is disclosed. The rotor is a consequent-pole rotor having a rotor core, a plurality of magnets, and a plurality of salient poles. The stator includes a stator core and multiphase coils. Each coil is wound about the teeth by distributed winding, in such a manner as to wind two or more consecutive teeth in single winding. The opening degree each of salient pole opposed to the distal ends of the teeth is set greater than or equal to twice the opening angle of the distal end of each tooth.
