Abstract

PURPOSE: To increase the quantity of air and to improve the cooling effect by providing a tapered air-guide, which is opposite to the fan mounted on the end face of the rotor, in the housing and by attaching a fan casing to the outer circumference of the air guide so that the space between the casing and the fan is gradually made greater.
CONSTITUTION: The radial cooling fan 8 is mounted on the end face of the rotor 4, the air guide 9 that is tapered inboard is provided between the fan and the side plate 6 of the frame. The fan casing 11 like a spiral stairs, for example, is attached to the outer circumference of the air guide so that the space A between the casing and the fan is gradually made greater as it extends to the end in the axial direction, an opening 15 is formed in the casing at which the space A becomes maximum. When the rotor is turned, cooling air F from the inlet 10 flows spirally along the fan casing 11 and is led from the opening 15 to the inside of frame 1, and discharged from the opening 16 to the outside after cooling.
