PURPOSE:To reduce the force required for working the mobile parts by winding the lead wire of the armature coil along the circumferential grooves of the electric insulator provided on the output shaft of the armature and introducing thereof to the housing section. CONSTITUTION:The field magnet 5 is fixed on the inner wall of the casing of the housing 1 composed of the casing 2 and the end bracket while the core 10 and the armature coil 11 are provided on the output shaft 9 supported rotatively with the bearings 6 and 7 to form an armature 8. Then, the electric insulator 13 having several circumferential grooves 12a and 12b are formed on the output shaft 9. The flexible conductors 14a and 14b separately connected to the lead wires 11a and 11b of the armature coil 11 is wound along the grooves 12a and 12b isolatedly and then, the ends thereof are separately connected to the power source terminals 15a and 15b provided on the end bracket 4. |
