Abstract
PURPOSE: To control the rotation velocity of a motor without using a frequency generator by controlling the rotation number of a motor in response to the detected output of a location detecting means to detect the location of a rotor.
CONSTITUTION: The frequency F of the current applied to a motor coil 12 is supplied from a push-pull 13 to a F-V conversion circuit 14 and the frequency is converted into voltage lovel. The output of the F-V conversion circuit 14 is supplied to the current supply terminal of the Hall element 4 through a variable resistor R5 and a resistor which are to regulate the level. For this reason, when the rotation number of the motor are less than the reference, the output of the F-V conversion circuit 14 and the operating current of the Hall element increase and the velocity of the motor is elevated up the reference.
