Abstract

The invention belongs to the technical field of electric motors, in particular to a safe and controllable electrical transmission device, comprising a generator unit and a motor unit; the generator unit at least includes an input shaft, an output shaft, and the generator unit has a permanent magnet rotor core. , The generator unit has winding rotor core, motor unit rotor end winding sheath 2 and motor unit rotor end winding sheath 3; after driving equipment (such as motor, heat engine) drives the input shaft of the electrical controllable start transmission device, The electrical controllable starting transmission device can smooth the torque of the output shaft through the external resistance and power electronic converter, and start the load smoothly to the final steady-state speed, so as to avoid the sudden change of the output shaft torque and excessive mechanical failures such as shaft breakage. It is suitable for crushers, fans, water pumps, compressors and other loads, and can reduce the problem of serious heating and small starting torque caused by the long duration of the starting high current of the driving motor.
