Title:
EMBEDDED MAGNET DYNAMO-ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JP2015073417
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an embedded magnet dynamo-electric machine, the torque characteristics of which can be enhanced by reducing the leakage flux of a permanent magnet.SOLUTION: A embedded magnet dynamo-electric machine includes a stator around which a coil is wound, and a rotor 30 where the outer peripheral surface of a cylindrical rotor core 40 is arranged to face the inner peripheral side of a stator through a gap, and a pair of permanent magnets per pole are embedded in V-shape so as to spread to the outer peripheral side in the peripheral direction of the rotor core 40. A flux barrier is formed between the inner peripheral edge of the pair of permanent magnets in V-shape, and projecting in the d-axis direction from the inner peripheral edge P1 of the gap side magnetic pole face of the permanent magnet. Following relation is satisfied 0.2≤Y/X≤0.3, where Y is the projection amount, and X is the distance between both ends P1, P2 of the gap side magnetic pole face in the d-axis direction.
