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.

Abstract: The present invention relates to the technical field of design and manufacture of magnetic couplings and provides a self-alignment protection device for permanent-magnet coupling, the self-alignment protection device comprises a first rotor and a second rotor respectively in fixedly connection with a load shaft (8) and a driving shaft (9), the first rotor and the second rotor being respectively mounted with permanent magnets that are mutually coupled to transmit torque, the first rotor and the second rotor are respectively configured with an inner conical surface and an outer conical surface that are coaxial and have mutually matching tapers, the self-alignment protection device further comprises an axial adjustment mechanism for adjusting the relative axial position between the first rotor and the second rotor. This technical solution solves the technical problem that the existing magnetic couplings are inconvenient to install and adjust.
