Abstract
PURPOSE: To ensure an accurate stoppage in a short time, by giving a rotary movement to the rotor up to the stop control range in a higher speed than the velocity immerdiately before stoppage when a stop instruction is given after detecting the range necessary for the stop control and then driving the rotor in a low speed and in the stop control range.
CONSTITUTION: The magnetic flux detector 4 detects the magnetic flux of the magnet 3 of the rotor 2 which is driven by the motor 1. The output detected by the detector 4 is compared with the reference value corresponding to the stop position through the comparison part 5, and then the output which varies plus and minus centering on the reference value is supplied to the control circuit 9. At the same time, the velocity of the motor 1 driven by the control of the motor driving circuit 21 is detected by the velocity detector 11 to be applied to the circuit 9. Then the zero-level of the signal detected by the comparator 5 is applied to the velocity setter 17 via the circuit 9 and in the form of the stop position of the motor 1, and the motor 1 is accelerated up to the 1st low-speed set value with the rotor 2 turned in the stop position range. Within this range, the motor 1 is driven by the 2nd set value lower than the 1st set value. Thus the rotor 2 can be stopped quickly at the stop position.
