ABSTRACT:
A motor coil structure has a lamination of in-slot coils incorporated into slots in a stator core and inter-slot connecting wires individually connecting to the end faces of the in-slot coils. Each of the inter-slot connecting wires is in the form of a bar such that the in-slot coils received in two different slots spaced away from each other by slots equal in number to n-1 (where n is the number of phases). Since the space factor depends on the lamination of in-slot coils in the slot, any clearance in the slot can be eliminated to improve the space factor compared with a motor coil structure in which a coil is formed by binding and winding a plurality of wires.
