Abstract

PURPOSE: To simplify the control circuit of a brushless motor by controlling the torque of the motor under the control of drive currents flown through the respective phases.
CONSTITUTION: A brush angle γ is provided by a torque instruction 4 for an angle signal 3 detected by a position detector 2 directly coupled to the rotor of a brushless motor 1 to thereby produce a drive signal 6 indicating that the phase is displaced by γ from the signal 3. This drive signal becomes a drive current 8 by a current control power amplifier 7 to energize the windings of the respective phases of the motor 1. Thus, it does not control the absolute value of the current in the power amplifier, but control the phase of the angle signal of the rotor thus detected by the position detector. Accordingly, it does not necessitate a multiplier, but can simplify the control circuit.
