Abstract

PURPOSE: To improve cooling effect and prevent the occurrence of overheat troubles by providing a guide cover outside the outer casing of a totally enclosed construction motor and making a motor shaft hollow to flow cooling air around the outer surface and in the shaft.
CONSTITUTION: At the back of a motor of a totally enclosed construction used for metal cutting work, etc., a cup-shape guide cover 30 is attached and inside the cover, a fan 28 is provided. Around the outer casing bracket 10 of the motor, plural radiating ribs 12a∼12c extending in the radial directions are provided and a center hole 22 is made through a motor shaft 20. By so doing, cooling air flow by the fan 28 is divided into the flow of arrow mark A guided by the guide cover 30 and the radiating ribs 12 of the outer casing bracket 10 and that of arrow mark B introduced into the hollow hole 22 of the motor shaft, and heat can be taken away efficiently from the radiating ribs 12 and the hollow hole 22.
