Abstract

Cooling and silencing of a motor, consisting of a stator and rotor mounted in the frame of a disc refiner for driving the working discs, by passing the cooling air through openings in the sides of the frame and causing it to enter the stator through the two end walls thereof and to leave radially then passing the air through the hermetically sealed stator casing to a space above this and thence to atmos. through a collector outlet, while being subjected to sound damping by an acoustic damping device.
