Abstract

PURPOSE:To eliminate the torque variation of a DC brushless motor by a method wherein a reference exciting current value required for the generation of a desired torque corresponding to the magnetized status of a rotor from a memory circuit is multiplied by a motor control signal and the multiplied value is supplied to armature coils. CONSTITUTION:The set value of each exciting current ID1, ID2 corresponding to the rotating angle of a rotor LM detected by a shaft encoder 2 is read out from a memory circuit 3. Meanwhile, an arithmetic circuit 4 multiplies the reference set values of the exciting currents ID1, ID2 by a control signal Ea value to calculate the magnitude of the exciting currents which are proportional to the control signal Ea. Power amplifiers 5, 6 perform pulse width modulation for the exciting currents ID1, ID2 in accordance with the digital signal supplied from the arithmetic circuit 4 to supply the exciting currents ID1, ID2 to armature coils L1, L2. The sum T0 of torques T1, T2 acting to the rotor LM by the controlled exciting currents ID1, ID2 becomes constant as shown in (b).
