Title:
SERIES MAGNETIC CIRCUIT-TYPE DOUBLE-LAYER HYBRID PERMANENT MAGNET MEMORY MOTOR
Document Type and Number:
WIPO Patent Application WO/2020/191815
Kind Code:
A1
Abstract:
Disclosed is a series magnetic circuit-type double-layer hybrid permanent magnet memory motor, comprising a stator, an armature winding, a hybrid permanent magnet rotor, and a rotating shaft. A rotor core of the hybrid permanent magnet rotor is provided around the outer portion of the rotating shaft; the stator is provided around the outer portion of the hybrid permanent magnet rotor; the armature winding is provide on the stator; each pole of the rotor core is provided with a radially-magnetized first permanent magnet, two tangentially-magnetized second permanent magnets, and an I-shaped magnetic barrier; the first permanent magnet is placed close to an air gap side in an I shape; end portions, far away from the rotating shaft, of the two second permanent magnets are respectively placed close to one end of the first permanent magnet; the I-shaped magnetic barrier is provided between end portions, close to the rotating shaft, of the two second permanent magnets; and the coercive force of the second permanent magnets is larger than that of the first permanent magnet. The problems of a narrow magnetic field regulating range and high required magnetic field regulating current of a conventional series magnetic circuit structure can be effectively solved, and the risk of load demagnetization when the motor operates can be reduced at the same time.
