Series magnetic circuit type variable flux memory motor with multiple low coercive force permanent magnet structures

The invention discloses a series magnetic circuit type variable flux memory motor with multiple low-coercivity permanent magnet structures, which comprises a stator, an armature winding, a rotor, a first layer of permanent magnets and a second layer of permanent magnets, the first layer of permanent magnets and the second layer of permanent magnets are arranged on the rotor, the first layer of permanent magnets comprises a plurality of low-coercivity permanent magnets, and the second layer of permanent magnets comprises a plurality of low-coercivity permanent magnets. The second layer of permanent magnets comprises a high-coercivity permanent magnet and a low-coercivity permanent magnet, and the high-coercivity permanent magnet and the low-coercivity permanent magnet of the second layer of permanent magnets form a series magnetic circuit structure. By changing the magnetization direction of the low-coercive-force permanent magnet in the double-layer permanent magnet, the motor has good load magnetic stabiliza
