Abstract
The invention relates to a double-layer winding layout method suitable for asymmetrical winding machine. The method is implemented by three main steps: 1) the design of the initial double-layer winding layout structure for each machine unit, which is based on the principle of the largest number of spokes belonging to phase A; 2) rearranging the number of spokes in positive (e.g., labeled a-phase belt) and negative sectors (e.g., labeled x-phase belt) belonging to phase A for making slot numbers equally divided; 3) solving the serial number of the stator slot in reverse to get the final winding layout schemes which contain multiple layout structures for one slot-pole combination. The method of the present invention improves the conventional star-of-slot theory based on the distribution characteristics of the asymmetrical windings, perfects the general design theory of double-layer asymmetrical winding structure.
