Abstract
PURPOSE: To reduce the size and weight of a rotary position detector and readily start a brushless servo motor by starting the motor using an oscillator as a synchronous motor.
CONSTITUTION: When a switch 6 is closed and a switch 7 is opened to generate a low frequency signal from an oscillator 8, a motor 3 is started as a synchronous motor by a trigonometric function generator 9 and a motor controller 2 to start rotating at low speed. An origin signal is detected within one revolution of the motor 3 to thereby open the switch 6 and close the switch 7. The generator 9 counts the number as defined by the number of poles of the motor 3 to generate a sine wave from a ROM or the like to thereby drive the motor 3 as a brushless servo motor.
