ROTATING ELECTRIC MACHINE AND ELEVATOR HOISTING MACHINE

摘要

In a rotating electric machine, a plurality of rotor magnetic pole portions each provided on a rotor yoke are arranged in a space between the rotor yoke and a stator at intervals in a circumferential direction. Each of the rotor magnetic pole portions has: a permanent magnet provided on the surface of the rotor yoke; and a magnetic pole piece made of a magnetic material and overlapping the stator side surface of the permanent magnet. The permanent magnet has an axial line tilted in a circumferential direction of the rotor with respect to an axial line direction of the rotor. The magnetic pole piece has a magnetic pole piece main body portion disposed over the region of the permanent magnet in the axial line direction of the permanent magnet. The sides of the magnetic pole piece main body portion are formed tilted in the circumferential direction of the rotor with respect to the axial line direction of the rotor.
