The structure diagram of three-phase reluctance stepping motor model is shown in the overview diagram. Its stator and rotor cores are made of silicon steel sheets. There are six magnetic poles on the stator, each two opposite magnetic poles are wound with the same phase winding, and the three-phase winding is connected into a star as the control winding; There is no winding on the rotor core, only four teeth, and the tooth width is equal to the stator pole shoe width.
