PURPOSE:To protect an electric circuit and prevent a resin frame from firing by connecting a device for protecting a circuit from an overcurrent in series with the electric circuit and by providing the device in the resin frame or on a housing. CONSTITUTION:A molded motor 10 is formed with a molding resin 26, uniting a stator core 12, a toroidal winding 14, a bracket 16, one end side of a lead wire 20, a leader line 22 and a fuse 24 in a body and forms a resin frame 28. By the fuse 24 to be an overcurrent protective device, the lead wire 20 from an external circuit such as a drive circuit and the leader line 22 from the toroidal winding 14 are connected in series. Thereby, even if a breakdown occurs in the molded motor and the overcurrent flows, the fuse melts by the heat caused due to the overcurrent and prevents the overcurrent beyond that from flowing. Therefore, the electric circuit is protected and the firing caused from the resin frame can be prevented. Also, the resin frame can be formed in the irreducible minimum size of a demand. |
