ABSTRACT:
In a circuit-integrated motor, it is an object of the invention to solve a problem that high power output is hampered by a heated electronic component, and to provide a compact high-power motor with a self-cooling fan which is capable of affording a significant cooling effect on the electronic component and winding wire. A self cooling fan (15) disposed close to and in an opposed relation to a top face of a rotor frame (11) has a peripheral-face opening (16), and an electronic component or a radiator attached with the electronic component is located in the course of a flow passage (17) of cooling air guidedly discharged from the peripheral-face opening (16).
