A two-phase electric excitation stepping motor

Abstract

The invention provides a two-phase electrical excitation step motor, and belongs to the technical field of a special motor. The two-phase electrical excitation step motor comprises a stator iron core, a rotor iron core, an excitation winding, an armature winding, a stator isolation block and a shaft, and is characterized in that eight uniformly distributed rotor poles are uniformly distributed on the rotor iron core fixed on a shaft; the pole arc mechanical angle of each rotor pole is 22.5 degrees; the stator iron core consists of two fan-shaped sub iron cores; two armature stator poles are arranged at the edge of the fan shape of each sub iron core; an excitation stator pole is arranged in the circular arc center line position of each sub iron core; the excitation winding is wound on the excitation stator pole. The step motor can realize the step operation by utilizing a switch magnetic resistance motor after the failure of the excitation winding, so that the characteristics of high efficiency, work reliability and good speed regulation performance are realized. The motor excitation winding is an integrated winding; the magnetic path is short; the copper loss and iron loss consumption is low; the efficiency is high.
