Abstract

PURPOSE: To reduce torque ripples by making the terminal volatges of current- sensing resistors connected in series with stator coils which supply power-amplifier outputs analogous to the voltages generated by Hall elements which sense the positions of magnetic poles of a rotor.
CONSTITUTION: The output terminals of Hall elements 5 and 51 which sense the positions of the magnetic poles of a rotor are connected to the inverted and non- inverted input terminals of operation amplifiers 7 and 71 through resistors 63 and 64, and 68 and 69, rewpectively. Stator coils L1 and L2 and current-sensing resistors 67 and 74 are connected to the outputs of the operation amplifiers 7 and 71 through power transistor Tr1 and Tr2, and Tr3 and Tr4. The connecting points of the current sensing resistors 67 and 74 and the stator coils L1 and L2 are connected to the inverted input terminals of the operation amplifiers 7 and 71 through feedback resistors 65 and 70.
