Disclosed is a multi-gear torquer with end covers on both sides of the casing. An input shaft and an output shaft are respectively arranged at the center of the two end covers. A sun gear is fixed on the input shaft and moves along a planet gear engaged in the transmission mechanism. The planet gear meshes with a gear ring and moves around the sun gear, then the planet gear drives the turntable centrally fixed with the output shaft connected to the load end. The multi-gear torquer disclosed herein has the following advantages: large output torque and high mechanical efficiency, and it can be used as power transmission equipment for a car or a train and used as other mechanical transmission equipment.

A motor with a variable-speed torque converter is disclosed. A rotor of the motor has a common permanent magnet structure. Permanent magnets are disposed on the rotor. The variable-speed torque converter includes a wheel disc, a wheel ring, a roller, a transmission gear II, a transmission gear III, a round wheel, an annular gear, a driving gear, turning discs, a transmission shaft, and an output shaft. The driving gear fixedly connected to the transmission shaft of the motor drives the transmission gear. The transmission gear is in contact with the annular gear. The transmission gear rotates around the driving gear to drive the wheel disc to rotate together. The wheel disc is fixedly connected to the output shaft to drive a driving wheel to rotate. Therefore, a working capability of the motor is enhanced. The converter can be applied to an electromotor, a generator, or any other power device.
