Title:
END WINDING FLUX MOTOR
Document Type and Number:
WIPO Patent Application WO/2022/121253
Kind Code:
A1
Abstract:
Disclosed is an end winding flux motor. The flux motor is used for being axially connected to the end of a conventional motor, and a stator winding of the conventional motor comprises an end winding protruding out of the end of a stator. The end winding flux motor comprises an end extension member, a rotor yoke and magnetic steel. One end of the end extension member is connected to the stator, and the end winding is wound on the end extension member, so that the end extension member and the stator share one winding; the rotor yoke is provided at the end of the end extension member far away from the stator, and the rotor yoke and the rotor are connected to the same motor shaft; the magnetic steel is provided between the end extension member and the rotor yoke, the magnetic steel is connected to the rotor yoke, and a gap is reserved between the magnetic steel and the end extension member. According to the end winding flux motor disclosed in the present invention, the end winding of the motor is utilized by means of the mode, so that power density of the motor is improved, the heat dissipation capability of the end winding is improved, and a "torque-current ratio" of the motor is increased.
