PURPOSE:To eliminate erroneous function due to noise by arranging an encoder and a controller on a motor body integrally therewith and oppositely to load side and arranging the sensor element in an encoder and a shaper circuit on the circuit board of the controller. CONSTITUTION:A rotation detecting section 6 and a shaper circuit 11 constitute an encoder. A control circuit 12a and a main circuit 15a constitute a controller. They are arranged on a motor body 2 oppositely to the load side. A winding 4 and a thermal protector 5 are connected through three lead wires 16 and two lead wires, respectively, with a main circuit board 15. The main circuit 15a is mounted on the main circuit board 15. A pulse disc 10 is coupled to the shaft 3 of the motor body 2. A light receiving element 10 is mounted on a control circuit board 12 while opposing to a LED 7 through the pulse disc 10 and an index scale 8. The shaper circuit 11 and the control circuit 12a are mounted on the control circuit board 12. |
