Abstract:
A motor stator for a motor is disclosed. The motor stator includes a stator body and a plurality of windings. The stator body includes a weld end, a crown end, and a plurality of slots arranged circumferentially and extending axially therethrough between the weld end and the crown end. Each winding including a phase lead, a neutral lead, and a plurality of coils. The plurality of coils include a same-layer lead coil including two legs that spans across multiple slots of the plurality of slots and that are inserted into respective slots at a same layer thereof. The same-layer lead coil positions the phase lead at the weld end. The neutral lead and welds joining the plurality of coils are all positioned at the weld end.
