Abstract
A method for producing stator windings for an electric motor, particularly a brushless motor, with n phases. The stator is disposed inside the rotor and its periphery is divided into a plurality of pole extensions. n conducting wires are then wound around equiangularly spaced groups of polar extensions forming n first coils. The wires are then wound around further groups of polar extensions, adjacent to the first groups, avoiding any superpositions between adjacent coils formed by a same wire. The process is then repeated so that the successions of coils formed by each of the wires is progressively superimposed to the successions of coils formed by the other wires, forming n equiangularly spaced spirals.
