Winding Insertion Method

Before inserting windings into shaded pole motors, place polyester film blue shell paper in the stator core slots. When inserting the coils, try to pinch them flat with your hands. Use your right hand to insert one end of the coil into the core slot, and use your left hand to pull the other end of the coil into the slot opening from the other side of the stator. Use a slotting tool to neatly insert the wires into the slot, arrange them neatly, and ensure that both ends extend evenly. Arrange the outer-slot parts at both ends of the coil into a drooping arc shape, cut off the binding wire that binds the coil, and use a slotting tool to cover the wires with slot insulation.

Shaping and Wiring

After the main winding is inserted, the inserted coil needs to be shaped so that the drooping arc on the inner side of the coil end is larger than the inner diameter of the stator core to avoid hindering the rotor assembly. The outer arc of the coil is smaller than the outer diameter of the stator core to ensure a certain distance from the end cover after assembly. After the coil is shaped, insert the magnetic shunt sheet.

Correctly connect the face wires and bottom wires of each coil according to the principle of reverse series connection to form a winding, and connect the lead wires. The common method is to put the connecting wires between each phase group into the gap at the position of the magnetic shunt sheet after covering them with insulating tubes, and bind the two lead wires.
