PCT No. PCT/JP83/00439 Sec. 371 Date Aug. 17, 1984 Sec. 102(e) Date Aug. 17, 1984 PCT Filed Dec. 16, 1983 PCT Pub. No. WO84/02619 PCT Pub. Date Jul. 5, 1984.A synchronous motor control system includes a sensor (112) for sensing the rotational angle of a synchronous motor (101), and a control circuit (108) for generating a sinusoidal value corresponding to the rotational angle sensed by the sensor (112) and for multiplying the sinusoidal value by an effective value current command. The multiplied output of the control circuit (108) is applied as a current command value to the armature winding of the synchronous motor (101). In this case, the arrangement is such that the control circuit (108) compensates the sensed rotational angle by the actual velocity of the synchronous motor (101) or by a rotational command velocity for the synchronous motor.
