Abstract
A magnetic coupling, includes a driving rotor sleeved on the driving shaft, a driven rotor sleeved on the driven shaft, external magnets mounted on the driving rotor and internal magnets mounted on the driven rotor and located on the inner sides of the external magnets; a plurality of internal magnets are arranged and uniformly distributed along the circumferential direction of the driven rotor; the external magnets and the internal magnets are aligned one by one along a radial direction; the internal magnets and the external magnets are magnetized along the radial direction; adjacent internal magnets have opposite magnetizing directions, and adjacent external magnets have opposite magnetizing directions; magnetic poles of the internal magnets are opposite to magnetic poles of the corresponding external magnets, and the driving rotor and the driven rotor form a working magnetic circuit through a magnetic field generated by the external magnets and a magnetic field generated by the internal magnets, wherein at least the external magnets are magnet exciting coils that generate a working magnetic field through power supply.
