EMBEDDED PERMANENT MAGNET TYPE ROTATING ELECTRIC MACHINE

摘要

An embedded permanent magnet type motor, which has one pole configured of two permanent magnets and has a plurality of poles of permanent magnets embedded in a rotor, includes a rotor whose magnet embedding holes communicate with a rotor outer periphery. The rotor has, between adjacent poles, a q-axis projection projecting in a direction away from a rotor rotation center. The magnet embedding holes are disposed so as to form an inverted V shape. An outer peripheral edge portion on the outer side of the permanent magnets has a curvature radius smaller than the distance from a rotation center axis to a rotor outermost peripheral portion. Circular intermediate plates of an outside diameter larger than the outside diameter of rotor steel plates are provided in intermediate positions in the rotor in a rotor rotation axis direction.

1. An embedded permanent magnet type rotating electric machine which has one pole configured of two permanent magnets and has a plurality of poles of permanent magnets embedded in a rotor, wherein
one or a plurality of disk-shaped intermediate plates, an outer periphery of which is substantially circular, are each disposed in an intermediate position between adjacent rotor steel materials in a rotor axis direction.
