PURPOSE:To generate an armature torque in response to a load and to always supply the prescribed constant armature current even if the speed of a motor increases by providing control means for supplying an armature current proportionally to the torque. CONSTITUTION:The first and second shafts 1, 2 are disposed on the same axis, and are rotatable with respect to a case 8 via bearings 3-7. Splines are respectively formed at the outer ends 1a, 2a of the shafts 1, 2, coupled with other shafts, and a torque detector T is formed between the opposed inner ends. A motor 11 is composed of a yoke 8a for forming the middle part of the case 8, a magnet 12 secured to the symmetrical position of the inner surface of the yoke 8a, and a rotor 13 rotatably disposed on the periphery of the shaft 2. An armature current is controlled proportionally to the rotary torque detected by the detector T. |
