Description

Technical Field

[0001] The utility model relates to the technical field of stepping motors, and particularly relates to a new lead type stepping motor stator structure. Background Art

[0002] At present, there are generally two types of stator structures for hybrid stepping motors on the market. One is to set plug-in terminals through a circuit board. Although this structure is convenient for plug-in assembly, its volume is too large, which is not conducive to space design, and there is also a problem of poor plug-in contact. The other is to directly lead out leads from the windings of the stator winding assembly. Although this structure has a small volume and no problem of poor contact, this structure is complex to operate. In order to prevent short circuits, heat shrinkable tubes need to be sleeved for insulation, and in order to fasten the leads so that they do not fall off, glue needs to be applied for fixed connection, resulting in low production efficiency and high labor costs, and automated production cannot be achieved. Therefore, it is necessary to further improve the lead structure of the stepping motor stator structure. Summary of the Utility Model
