A DC motor having an electronic commutator including, inter alia, an annular insulating support (410) which carries at its periphery (4101) a ring (4102) which is bordered on one side by a lateral rim (4103) having a lesser diameter. The ring (4102) is arranged to define teeth (4104) having a rectangular cross-sectional shape (4106) and defining therebetween gaps (4108) which are each provided in their middle with a mushroom-shaped element (4000). Each mushroom-shaped element has a foot (4001), which is higher than the depth of the gap (4108), and a head (4002) which overhangs both the teeth (4104) which surround it and the rim (4103). The rim (4103) is provided with slits (4003) located in alignment with the feet (4001).
