Abstract
A motor-driven apparatus includes a pump and a servo motor connected respectively to outer sides of opposed upstanding support plates. A pump shaft and a servo motor shaft extend horizontally toward each other into a space between the support plates and are coupled together by a flexible coupling. The servo motor includes a fan cover enclosing and spaced from a motor frame of the servo motor. A cooling fan disposed inside the fan cover circulates air in the space between the fan cover and the motor frame to air-cool the motor frame.
