Abstract

PURPOSE:To absorb the dispersion of the sensibility of a Hall element by transmitting an output of the Hall element to a power supply circuit through buffer amplifiers and arithmetic circuits while controlling the amplification degrees of the buffer amplifiers in response to the sum of the absolute values of each output of the arithmetic circuits and an output of the power supply circuit in response to the minimum value of the absolute values. CONSTITUTION:Outputs from Hall elements 1-3 are transmitted over armature coils 4-6 through buffer amplifiers 21-23, subtraction circuits 31-33 and a power supply circuit 80. An error amplifier 51 controls the amplification degrees of the buffer amplifiers 21-23 in response to difference between the sum of the absolute values of outputs from the subtraction circuits 31-33 and a reference value at that time. An error amplifier 130 controls output currents from the power supply circuit 80 in response to difference between the sum of the minimum value of the absolute values of outputs from the subtraction circuits 31-33 and a command signal and supply currents to the armature coils 4-6.
