WebDec 11, 2024 · Direct torque control (DTC) is a third method used in variable-frequency drives to control the torque (and therefore the speed) of three-phase AC motors. DTC involves calculating an estimate of the motor’s magnetic flux and torque based on the motor’s measured voltage and current. Stator flux linkage is estimated by integrating the … WebIn electronics, a choke is an inductor used to block higher-frequency alternating currents (ACs) while passing direct current (DC) and lower-frequency ACs in a circuit. A choke usually consists of a coil of insulated wire often wound on a magnetic core, although some consist of a doughnut-shaped "bead" of ferrite material strung on a wire.
