The present invention relates to principles for cooling the stationary winding of an induction motor, said winding being positioned outside the movable armature. The cooling can be achieved by means of cooling fins, openings allowing the ventilation of the winding with or without a fan, a fluid circuit outside the bowl, a fluid circuit inside the bowl, a fluid circuit inside the winding, and/or the addition of heat pipes inside the bowl. This motor as presented can be used, without limitation, inside loudspeakers or vibrators.
