PURPOSE: A motor control apparatus is provided to detect a stimulus position based on ascending and descending of a pulse signal, thereby effectively suppressing sinusoidal wave distortion of a modulated wave signal. CONSTITUTION: A motor(10) is operated with power of a DC power source(E). A driving circuit(4) controls a waveform of motor driving current. An inverter circuit(6) outputs a DC current of the DC power source to the motor by converting into an AC motor driving current. The inverter circuit is arranged by assembling six switching devices(Tr1-Tr6). The switching device is turned on/off by a PWM(Pulse Width Modulation) driving signal from the driving circuit. |
