Abstract:
1. A method of preparing a winding for an n-phase electric motor, said method comprising: (a) continuously and simultaneously winding a 2n-plurality of insulated conductors in a same direction around a mandrel to obtain at least a 2n-plurality of individual windings; (b) axially shifting the conductors with respect to the formed individual windings to a position adjacent the individual windings obtained in step (a); (c) repeating steps (a) and (b) a predetermined number of times, the repeating of the steps (a) and (b) being accomplished by winding the 2n-plurality of insulated conductors around the mandrel in the same direction as step (a); (d) interconnecting pairs L(y) and L(y+n) of said conductors at an end of the overall winding, where y is an integer varying from 1 to n, such that conductors L(y) and L(y+n) are configured to conduct current in opposite directions (e) flattening the winding by collapsing first and second parts of each individual winding upon itself such that the parts of the winding are adapted to conduct current in the same direction are placed adjacent to each other.
