Abstract

PURPOSE:To obtain a simple Hall motor controlling circuit by providing the first conductive type differential transistors inputting the output of Hall elements and the second conductive type transistors receiving the outputs of the first transistors and outputting from the collectors to a constant current load provided in the collector circuits. CONSTITUTION:A rotary position detection signal from a Hall element H is inputted to differential transistors Q1, Q2 in a Hall amplifier A1. A differential amplification signal obtained from the collector of the Q7 in a current mirror circuit having transistors Q6, Q7 and resistors R6, R7 is inputted to the amplifying stages of transistors Q9, Q10. The voltage gain of the amplifier A1 is set by the feedback circuit of resistors R2, R3. The output impedance becomes large by a constant current circuit of resistor R5 connected to the collector of Q9, Q10 and the transistor Q4. The output current of the amplifier A1 is amplified through a drive circuit A2 to drive a stator coil and to limit the amplitude via the transistor Q5.
