Abstract
The present disclosure relates to a stator of a motor comprising three phase windings, wherein each phase winding comprises a first winding group and a second winding group configured as multiple layers, the first winding group and the second winding group each have multiple adjacent sub-winding groups arranged side-by- side, and each of the sub-winding groups is formed by connecting formed conductors corresponding to a same phase in series; on the outermost and / or innermost layer, the formed conductors at ends of the sub-winding groups in the first winding group are connected to the formed conductors at ends of the sub winding groups in the second winding group
