1. A motor comprising a housing having a cylindrical recess located and configured to receive and center a cylindrical wound stator, the stator having an electrical connection assembly with transversely extending connecting tabs, the housing having a lateral protrusion for connection with a complementary connection assembly, wherein the stator, fitted with the electrical connection assembly, is overmolded with an electrically insulating resin to form a rigid block with no moving parts intended to be housed in the housing and to receive a rotor, said stator being rigidly linked to the electrical connection assembly by overmolding, without connection by a flexible cable, wherein the housing is formed from a single piece, with a tubular body closed by a bottom and open at its opposite end, the housing having an upper part with an axial opening for introducing and positioning the overmolded stator and a radial opening for making the electrical connection with an external connector, and wherein the housing has, in a rear part of the housing, a first angular wedging feature complementary to a second angular wedging feature provided at a rear part of the overmolded electrical connection assembly.
