Abstract
PURPOSE:To reduce the dimension of the motor driven power steering device by installing each revolution angle sensor onto the upper side and lower side column shafts and detecting the torsion of the column shaft by these revolution angle sensors. CONSTITUTION:A direct drive motor DM consists of a motor 7 and a stator 8, and said stator 8 is fixed onto a motor case 9. A slit plate 12A is fixed onto the lower edge part of an upper side column shaft 2A, and a revolution angle sensor 12 having the light transmitting and receiving bodies, having the slit plate nipped, is arranged on the outer periphery of the slit plate. A revolution angle sensor 13 having the same constitution is arranged also on a lower side column shaft 2B. Since the torque generated on the upper side column shaft 2A can be obtained from the output voltage difference of the both revolution angle sensors 12 and 13 arranged in the motor case, the need of installing a torque sensor at the position different from that of the motor DM in the conventional is avoided, and the small-sized device can be obtained.
