動機の冷却フアン装置。 a cooling fan that is inserted into the shaft of a rotary electric motor and is movable in the axial direction of the shaft with a thrust corresponding to the rotational speed of the fan; a friction plate that transmits the rotational force of the rotary electric motor to the cooling fan; is pressed with a predetermined pressing force against the thrust, and when the rotational speed of the rotary electric motor reaches a set value, it is compressed by the thrust of the cooling fan to reduce the frictional force between the friction plate and the cooling fan. A cooling fan device for a rotary electric motor, comprising a biasing member that causes a slippage in the rotational speed of the cooling fan with respect to the rotational speed of the rotary electric motor.
