The motor has a stator, a rotor (3) attached to a shaft so as to rotate with it, two bearing plates (4) with one bearing each for the shaft, and a tubular housing with the bearing plates attached to its ends. The housing is made of a good heat conductor. At least one of the bearing plates is made of plastic and has a heat extraction plate (9) on its side facing the rotor. |
