CONCENTRATEDLY WOUND PERMANENT MAGNET MOTOR, HOIST FOR ELEVATOR USING THE SAME, AND ELEVATOR

摘要

PROBLEM TO BE SOLVED: To provide a concentratedly wound permanent magnet motor, a hoist for an elevator using the same, and an elevator, capable of reducing noise without causing a large-sized and heavy weight construction of the motor.;SOLUTION: A concentratedly wound permanent magnet motor includes: a stator core 1 having a tooth 2 fitted to a back yoke 3; a stator 10 having a concentratedly wound coil 7 wound around the tooth 2; and a rotor 20 having a permanent magnet 12 fixed to a rotor core 11 and opposed to the stator 1 via a predetermined space. The tooth 2 and the back yoke 3 are made of different members, and the tooth 2 in a substantially Y-shape is fitted to a fitting recess 3a in the substantially Y-shape in the back yoke 3 to integrally constitute the stator core.;COPYRIGHT: (C)2015,JPO&INPIT
