ABSTRACT:
This motor includes an armature winding (12) equipped with conducting coils (A1 to A4, B1 to B4, C1 to C4) distributed into three phases and into two, lower and upper, layers. The lower coils (A1, A3, C1, C3, B2, B4) alternate with the upper coils (B1, B3, A2, A4, C2, C4). Each phase comprises a pair of diametrally opposed coils arranged in the lower layer and a pair of diametrally opposed coils arranged in the upper layer. These two pairs are linked electrically in parallel. Each coil includes two, lower (A11) and upper (A12), windings and two uninterrupted wound conductors (K1, K2) . linked electrically in parallel. Each conductor (K1, K2) forms the lower winding of a coil of a pair and the upper winding of the other coil of this pair, in such a way that these lower and upper windings are linked electrically in series.
