Stator for high-low-temperature vacuum stepping motor and winding method of stator

The invention relates to the technical field of stepping motor manufacturing, in particular to a stator for a high-low-temperature vacuum stepping motor and a winding method of the stator. An insulating device comprises a plurality of insulating pad units and a plurality of insulating sheet units, wherein the insulating pad units are matched with end planes, and the insulating piece units are matched with side surfaces; the outer end of each insulating pad unit extends out to form a transition portion; and the insulating pad unit is an elastic deformation structural member made of polytetrafluoroethylene. According to the stator for the high-low-temperature vacuum stepping motor and the winding method of the stator provided by the invention, when a winding wire presses the transition partextended from the insulating pad unit, the extension part of the insulating unit is elastically deformed, and an arc surface can be generated, so that the smooth transition of the coil and the insulating device at the transit
