The stator includes an iron core, a coil and an insulating material.

What are the commonly used materials?

Common materials; Silicon steel sheet, copper enameled wire, insulating paper, insulating paint, yellow wax pipe, bakelite board, cable tie.

What is the general production process?

Stator manufacturing is divided into three processes; Iron core molding, wire embedding and paint dipping.

The iron core is composed of several insulating silicon steel sheets. Select a piece of silicon steel with appropriate thickness, cut and shape it, stack several pieces to a certain thickness, bind and fix them with iron sheets, and embed them into the motor housing.

Wire insertion is to put the coil winding into the iron core slot. Organic mosaic and manual mosaic. There are many forms of stator coil wiring, including three-phase winding, primary winding and secondary winding, excitation winding, single-layer and double-layer winding, multipole winding and so on. Before embedding wires, pad one or two layers of insulating paper in the iron core groove, put the enameled wires with proper thickness and turns into the groove in turn, completely wrap the enameled wires with insulating paper, and then insert the bakelite board into the groove and seal it in the groove. Connect the wires by soldering, put on the yellow wax tube, and finally tie the coil.

After the embedding is completed, the stator is dried, dipped in insulating paint and dried.

It can only be used after inspection.

The slots on the iron core are stamped together with the whole.

The winding is copper enamelled wire.
