<P>PROBLEM TO BE SOLVED: To provide a permanent magnet-embedded electric motor capable of facilitating winding of a stator coil, reducing inductance of the stator coil, and reducing eddy current generated in a permanent magnet. <P>SOLUTION: A permanent magnet-embedded motor 1 comprises: a rotor 5 including a rotor core 6 having an outer peripheral surface constituted as a plurality of convex faces in which arcuate curved surfaces 7 are circumferentially and continuously arranged at equiangular pitches, and a plurality of permanent magnets 9 embedded in the rotor core 6 such that they are located on the inner diameter side of each of the arcuate curved surfaces 7; and a stator 2 including a stator core 3 constituted as an opening slot in which teeth 3b extend from an annular core back 3a inwardly in a radial direction and are arranged at equiangular pitches, and a stator coil 4 consisting of a plurality of concentrated winding coils 4a each wound on each of the teeth 3b by concentrated winding. <P>COPYRIGHT: (C)2013,JPO&INPIT |
