INDUCTION SYNCHRONOUS MOTOR

摘要

PROBLEM TO BE SOLVED: To provide an induction synchronous motor in which the assembling workability of a rotor is improved while reducing production costs sharply, and operational performance of the motor is enhanced. SOLUTION: A plurality of diecast secondary conductors 5B are provided at the peripheral part of a rotor yoke part 5A constituting the rotor 5 of an induction synchronous motor 2. End rings 68 and 69 are diecast integrally with the secondary conductors 5B at the peripheral part of the opposite end faces of the rotor yoke part 5A. A permanent magnet 31 is inserted into a slot 44 penetrating the rotor yoke part 5A. Openings at the opposite ends of the slot 44 are closed by a pair of end face members 66 and 67 made of a nonmagnetic body. One end face member 67 is secured to the rotor yoke part 5A through one end ring 69 at the time of molding the secondary conductors 5B and the end rings 68 and 69. The other end face member 66 is secured to the rotor yoke part 5A by means of a securing metal (rivet) 66A. COPYRIGHT: (C)2005,JPO&NCIPI
