The rotor is a permanent magnet, magnet is salient pole (Electrical pure iron or silicon steel sheet, etc. ), there is no magnetization, the same as the salient generator rotor. Such as shown in figure cylindrical rotor, from the reluctance of the stator pole looked rotor, the rotor at any position are the same, won't produce torque. And as shown in the salient pole rotor can generate electromagnetic torque, turns the load torque. As shown in figure type is VR step motor, the outer stator poles to n. Rotate speed, the electromagnetic force that appeal to balance the load torque, load Angle S work. Informed by electromagnetic induction and electromagnetic attraction of torque TZ reduce rotor reluctance to trend direction, as shown in figure assume counterclockwise torque is positive, clockwise torque is negative. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
