magnetically driven couplings;  Optimize design;  Select

The magnetic drive coupling is a non-contact type power transmission device. On the basis of deriving the magnetic torque formula of the magnetic drive coupling, various factors are analyzed and compared in the main parts of the magnetic coupling, and the optimization design idea is proposed, which solves the problem of the ratio of magnet length to air gap length, the problem of length-diameter ratio, the problem of maximum magnetic moment and shortest magnetic circuit, and the ratio of relative displacement angle and pole opening angle.
