PURPOSE:To obtain a molded motor in which a danger such as an ignition, etc., can be prevented by providing a temperature fuse in the vicinity of extrafine wirings to generate heat by an overcurrent formed part of printed wirings for connecting a power source to a winding. CONSTITUTION:A winding 2 of a motor is wired via a printed board 9 buried in a frame 3. Leads 10 are connected to the board 9, and extended out of the frame 3 by a bushing 11. Two extrafine wirings 12 formed fine than other printed wirings are formed in parallel between a terminal 17 connected with a power source and a terminal 18 connected with the winding 2, and a temperature fuse A is provided between the wirings 19. If an overcurrent flows to the winding 2 of the motor, the wirings 19 on the board 9 generate heat due to an electric resistance. When the fuse A reaches a predetermined temperature, its interior is shut OFF to open between the terminal 17 connected with the power source and the terminal 18 connected with the winding. |
