The invention relates to a multiphase rotating motor which enables a magnetic potential slope intercoupled by a field magnet member and an armature member to be prearranged in order to control the detent torque to the needed change through providing the needed polar shape for the two magnetic poles of the field magnet member magnetic assembly and the antipode polar of the armature member electromagnet assembly; further balances the unwanted detent torque in order to ensure the flux concentration of the motor characteristic and the minimization of the flux loss and the interference effect almost without influence by arranging the multiphase. Moreover, more parallel air gaps in the three dimensional space of the motor is increased under the help of two or more magnetic tracks. The motor canobtain the benefits of higher torque output supply or simultaneous arrangement of multiple independent movable individuals in series under the finite movable direction space condition based on the different magnetic tracks corresponding to the electromagnet assembly of each phase unit with that of the other phase unit.
