Direct torque control is a motor-control method for ac drives that accurately regulates motor speed and torque without encoder feedback from the motor shaft. Eliminating encoders can simplify ...

This application note describes the Zilog Motor Control Technologies presenting the motor control strategies, the control strategy by motor type, as well as the Open- vs. Closed-loop speed control and ...

This White Paper will explain the three methods that are used to close the feedback loop around stepper motors in a control system. These three methods include ways to close the loop around a stepper ...
