In an apparatus for controlling static electronic components in the control circuit of a three-phase brushless electric motor, a single shunt device (RS) is used for limiting at least one of the phase currents (IF, I1, I2, I3) of the motor (MT) to a preset limit value. A signal generator device (GS) interrupts the switching of the static electronic components (T1, T2, T3, B1, B2, B3) when the voltage (VS) at the ends of the shunt device (RS) exceeds a preset limit current value. Phase current limitation of the motor (MT) is attained using a PWM technique, alternatively modulating two static electronic components (T1, B2 or B3; T2, B1 or B3; T3, B1 or B2) that are comprised in the electric circuit branch in which there is electric continuity at any instant of the control sequence.
