winding type permanent magnet coupling transmission device

摘要

winding type permanent magnet coupling transmission device comprising a permanent magnet rotor and a winding rotor that is coaxial with the permanent magnet rotor and with the ability to rotate relative to the permanent magnet rotor. an air gap (9) exists between the permanent magnet rotor and the winding rotor. The winding rotor is connected to a control structure (17) with the ability to adjust the winding rotor current / voltage. The control structure can control the winding rotor current or voltage to adjust the output torque of the transmission device, and a corresponding mechanical execution mechanism need not be arranged. Consequently, the transmission device has a simple structure and small energy loss.
