Abstract :
Direct torque control (DTC) is the latest AC motor control method developed by ABB. ACS600 is the first application utilising DTC. DTC is a control method that embeds a motor and inverter together and controls them together in an optimal manner. In DTC, all switch changes are based directly on the electromagnetic state of the motor. Optimum switching is determined for every control cycle on a time level of 25 microseconds. The switch positions of the power module are determined by the calculated stator flux and motor torque
