Abstract

PURPOSE:To improve the controllability of the subject motor by a method wherein the second rotor core, having the number of teeth same as that of the stator core and divided by permanent magnet, is added to the vernier type stepped motor, and the retentive torque is maintained when the motor is at standstill. CONSTITUTION:A DC exciting winding 2 is wound around the stator core 1, the rotor core 3 is fitted to a shaft 4, and the vernier type stepped motor is formed in such a manner that the number of teeth for the stator core 1 is varied from that of the rotor core 3. Also, another stator core 1A, which is the extended part of the stator core 1, and a rotor core 5, which is penetrated in the shaft 4 through the intermdiary of a non-magnetic sleeve 7, are provided and the same number of teeth are established for them. Accordingly, the vernier type stepped motor, having no detent torque, can have the detent torque, and the controllability of the motor can be improved.
