Abstract
PURPOSE:To provide a pulse motor with a function as a load detector, by detecting time lag between change corresponding to the change-over of an exciting coil phase and change resulting from the revolution of a rotor from the change of input currents. CONSTITUTION:An exciting phase of a pulse motor 2 is changed over by means of a drive circuit 1 receiving pulse input from a pulse oscillator 10. The variation of coil currents is detected as the change a of the voltage of external resistance, and input to a differentiator 11. A pulse generator 13 puts out a pulse c when the output b of the differentiator 11 exceeds set value, and a gate circuit 12 closes a gate during the time when the pulse is input and a variation portion shown in d is removed. A wave-form converter 15 is in ON due to a pulse resulting from the revolution of a rotor through an amplifier 14, and a comparator 16 using the output f of the wave-form converter 15 and the output e of a square-wave generator 17, which employs the output c of the pulse generator 13 as input, as input puts out a pulse shown in g. Thus, the magnitude of load applied to a shaft can be decided.
