Title:
AXIAL-GAP TYPE ROTATING-ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JP2005304245
Kind Code:
A
Abstract:

To provide an axial-gap type rotating-electric machine formed with permanent magnets on a rotor, capable of reducing leakage flux between the permanent magnets so as to increase generated torque by adding magnet torque to reluctance torque.

A body of the rotor 3 is fixed to a rotor shaft 2. The body of the rotor 3 is formed by laminating electromagnetic steel sheets 11 which is a ferromagnetic body. A plurality of the permanent magnets 12 are mounted in a circumferential direction in the electromagnetic steel sheets 11 as the body of the rotor 3. Air gaps 14 opening in the circumferential direction are formed between the permanent magnets 12 and the electromagnetic steel sheets 11 at a portion sandwiched between the circumferentially neighboring permanent magnets 12, 12.
