ABSTRACT:
A torque compensation system is disclosed for d.c. motor drives using field weakening for speed control. A diode switching matrix and a static divider are connected so that the divider receives signals which are functions of motor armature current and speed respectively, and delivers at its output a signal which is proportional to motor torque for adjusting the speed reference to the motor.
