The motor (1) has a circuit substrate (12) fixed to its casing (1), which includes an electrical circuit which supplies current to the stator (2). A fan (11) is used to displace air produced by turning of the rotor (6) and a pipe (21) guides part of the air, displaced by the fan, towards the stator (9). The motor has a radiator (3b) which extends from the stator (2), the air from the pipe (21) flows along the radiator (3b). The stator (2) has a central part (3), a core (4) fitted around the part (3) and a wire coil (5) wound around the core (4). The radiator (3b) extends upto the core (4).
