Coil winding method

1, single-layer coil, insulated wire wrapped around paper tube or bakelite skeleton. Such as a wave antenna coil in a transistor radio. Single-layer winding is a winding with only one effective side embedded in each stator slot, so its total number of coils is only half of the total number of motor slots.

2. Honeycomb type, the plane of winding the coil is not parallel to the plane of rotation, but intersects at a certain angle. Honeycomb winding method has the advantages of small volume, small distributed capacitance and large inductance. Honeycomb coils are all wound with honeycomb winding machines. The more folding points, the smaller the distributed capacitance.
