Electrical mechanics may specialize in working with certain types of apparatus, such as electric motors or transformers, or in performing certain functions, such as winding coils.

Prepare a jig for winding your coils by cutting a 3 cm by 16cm pieceofcardboard, folding it in half and securing with a small pieceofelectrical tape.

There are axial slots matching with the permanent magnets on outer peripheral of the rotator on the main motor shaft. The circulation winding coil is embedded in the slots.
