PURPOSE:To suppress the torque ripple of a motor by supplying the outputs of a plurality of magnetoelectric transducers through output balance regulating means and output current regulating means to a stator winding. CONSTITUTION:The outputs of Hall elements 1-3 are supplied through preamplifiers 100, 200, 300 and power amplifiers 400, 500, 600 to stator windings 7-9. The output of a comparator 700 is supplied to the preamplifiers 100, 200, 300 so that the sums of positive and negative outputs supplied from the preamplifiers 100, 200, 300 to the amplifiers 400, 500, 600 become equal. The amplification factors of the amplifiers 400, 500, 600 are controlled by the control voltage from the control voltage input terminal 20. |
