Abstract

PURPOSE:To suppress the decrease in the performance of the hybrid type step motor due to the interference of magnetic fluxes by winding at least one phase stator winding independently on two stators provided corresponding to two rotors aligned, reducing the rotor inertia and decreasing the length of the stator winding. CONSTITUTION:The rotors 22, 23 having a number of rotor teeth are aligned in parallel on the outer periphery on one rotor shaft 21. A rare earth metal magnet 26 magnetized in a direction of the rotor axis 21 is provided between the rotors 22 and 23. The stators 41 and 42 having four stator poles corresponding to the rotors 22 and 23 are provided between brackets 27 and 28, and stator windings are wound thereon for the phases A and B. Thus, since the outer diameter of the rotor can be reduced, the rotor inertia can be decreased, and since the stator winding is independently wound, the entire length of the stator winding can be shortened.
