Abstract: A winding type permanent magnet coupling transmission device includes a permanent magnet rotor and a winding rotor that is coaxial with the permanent magnet rotor and capable of rotating relative to the permanent magnet rotor. An air gap exists between the permanent magnet rotor and the winding rotor. The winding rotor is connected to a control structure capable of regulating the current/voltage of the winding rotor. The control structure is capable of controlling the current or voltage of the winding rotor, so as to regulate the output torque of the transmission device, with no need to configure any corresponding mechanical execution mechanism. Therefore, the transmission device has a simple structure and small energy loss.
