Abstract
PURPOSE:To make it unnecessary to adjust an encorder for zero detection at the time of assembling of a device by detecting zero based on the phase induced voltage induced to the stator winding. CONSTITUTION:At the time of start-up, a square wave signal is generated by a square wave signal generator 9 based on a U shape signal C S1. And, the zero crossing detection of the induced voltage for a stator winding of a motor 4 is made, and a square wave drive of the motor 4 is made based on the square wave signal before a zero signal Z from a zero signal generator 15 is transmitted. After transmitting the zero signal Z, a sine wave drive of the motor 4 is made based on a sine wave signal generated by a false sine wave signal generator 8. According to the constitution, an accurate adjustment is not necessary at the time of assembling of a device.
