PROBLEM TO BE SOLVED: To provide a molded motor capable of preventing the occurrence of electric corrosion even when subjecting an inner-rotor type molded motor to PWM control with an inverter circuit. SOLUTION: Conductive paint 36 is applied on the inner peripheral face of a molded motor frame 22. An output-side bracket 24 and a counter-output-side bracket 34 are short-circuited by the conductive paint 36. Consequently, it is possible to prevent the electric corrosion of bearings 30, 32.
