A magnetic induction coupler mainly comprises an outer wheel having a conducting strip rotor attached on its inner wall and a magnet stand located within the outer wheel, both arranged coaxially on a shaft. A number of permanent magnets are arranged around the outer wall of the magnet stand to form a multipolar magnetic field. A number of conducting strips are circularly distributed on the conducting strip rotor and electrically connected. The rotational motion of the outer wheel is mechanically decoupled from the magnet stand by two sets of bearings. To achieve relative motion between the outer wheel and the magnet stand, a motor is used to drive the outer wheel. As the outer wheel rotates, an induction torque produced by an electric current induced in the conducting strip rotor drives the shaft to move accordingly. Further, the magnitude of the induction torque is proportional to the motor speed.
