An electrical motor with variable reluctance and electronic commutation comprising a stator ring 1 containing contacts 10 provided with coils 11, the number of which is a multiple of the product of the number of commutators times the number 4 (pattern 4), and a rotor ring 2 containing teeth 20, the number of which is the same multiple of a prime number greater than the product "commutators x pattern 4", the rings 1, 2 being produced by stacking metal sheets cut out respectively as sectors of 2 to 5 teeth 12 and as sectors of 2 to 5 contacts 22, is characterised in that the residual air gaps 13, 23 formed by the side-by-side placement of the said sectors 12, 22 are located substantially in the median part of the contacts 10 and of the teeth 20 respectively. This characteristic makes it possible to eradicate the parasitic reluctance due to the assembly of metal sheets cut out sectorially in the rings. <IMAGE>
