Title:
LOW VIBRATION TORQUE PERMANENT MAGNET BRUSHLESS DIRECT CURRENT ELECTRIC MOTOR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/054282
Kind Code:
A1
Abstract:
A low vibration torque permanent magnet brushless direct current electric motor system. The permanent magnet brushless direct current electric motor of the present system is based on a three-phase six-state control mode, and has the two structural forms of a single stator core and a single rotor core, and a double stator sub-core and a double rotor sub-core; when the electric motor is in operation, in addition to the average torque for generating a drive load, the motor can also generate two vibration torques with the same amplitude and 180° electrical angle phase difference, suppressing and offsetting the vibration torque by means of the principle of peak and valley complementarity, and thereby achieving a permanent magnet brushless direct current electric motor with low vibration torque.
