Abstract

PURPOSE:To enable a DC brushless motor torque to linearly be controlled by a method wherein a constant current circuit which have stator coils connected between nodes and are connected in series with plural pairs of parallel circuits in a series circuit of a pair of transistors, is connected to a power source. CONSTITUTION:The transistors Q1-Q6 are ON-OFF controlled by a switching control circuit A1 based on rotational positions detecting signals from Hall elements H1-H3, thereby a power source voltage Vm being applied to the stator coils L1- L3 to cause the motor to be driven. At the time, the currents commutated through the coils L1-L3 are turned to currents to be attracted to the constant current circuit A2 and accordingly, the commutated currents can be controlled by the constant current circuit A2 and the constant current circuit A2 is varied, thereby enabling the torque of the motor to arbitrarily linearly be controlled. In addition, diodes D1-D6 are used for the protection against the inverse voltages between base emitters of the transistor Q1-Q6.
