PERMANENT MAGNET ROTATING ELECTRIC MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a permanent magnet rotating electric machine which can prevent a permanent magnet from being cracked even when the permanent magnet is magnetized. SOLUTION: The permanent magnet rotating electric machine includes a rotor core 32A in which two circumferential grooves 32C are formed toward a circumferential direction of the rotor core 32A near an axial end side of the permanent magnet 32B on the outer peripheral surface of the rotor core 32A. An adhesive for fixing the permanent magnet 32B to the rotor core 32A is coated on the circumferential groove 32C and the axial end face of the permanent magnet 32B. COPYRIGHT: (C)2005,JPO&NCIPI
