Abstract
A cooling device for an electric motor includes a plurality of inwardly projected stator poles arranged in a circumferential direction such that an axially extending space is defined between two adjacent stator poles. Coils are wound on the respective stator poles and coolers are disposed in the respective spaces such that each of the coolers is in thermal contact with its neighboring coils.
