Abstract
The invention relates to a permanent magnetic coupling torque-variable driver. The driver comprises a permanent magnetic rotor and a conductor rotor covering the external of the permanent magnetic rotor, and the circumference surface and the side surfaces of the permanent magnetic rotor are completely covered with the conductor rotor. The permanent magnetic rotor comprises fixed type permanent magnets, adjusting type permanent magnets and magnetizers arranged between the fixed type permanent magnets and the adjusting type permanent magnets. The fixed type permanent magnets and the adjusting type permanent magnets are alternatively arranged at intervals along the circumference or in the radial direction. The adjusting type permanent magnets are adjusted by an adjusting mechanism, so that relative positions of the adjusting type permanent magnets and the fixed type permanent magnets can change. The axial distance between the permanent magnetic rotor and the conductor rotor is constant. The permanent magnetic coupling torque-variable driver has non-load starting and stepless torque converting functions, has a speed regulation range of 0-97%, is low in heat generation rate, can fully utilize multiple surfaces of the permanent magnets to work, has better energy-saving efficiency, can insolate or reduce vibration transmission, and is more compact in structure.
