Abstract

The invention concerns an electric motor with fan and a cooling fan 2 for cooling of same. The axle 3 of the cooling fan 2 is coaxial with the axle 1 of the electric motor. In order for the electric motor to be able to operate as long as possible under exceptionally high usage temperatures, the electric motor comprises means 16, 17, 3 which halt the operation of the cooling fan 2 when the electric motor is surrounded by a hot air flow whose temperature is exceptionally high as compared to the normal operating temperature of the electric motor, and the electric motor's shell 9 is essentially surrounded by a ring-shaped mantle 10 such that between the mantle and the electric motor's shell there is an air flow channel 11 for cooling of the motor by means of the cooling fan 2 during normal usage, wherein the motor contains means of halting the air flow in the air flow channel 11 after the operation of the cooling fan has ceased. <IMAGE>
