Direct torque control (dtc) is one method used in variable frequency drives to control the torque (and thus finally the speed) of three-phase ac electric motors this involves calculating an estimate of the motor's magnetic flux and torque based on the measured voltage and current of the motor. Now a days brushless dc motors (bldc) are frequently used in many domestic and industrial applications ranging from servo to traction drives, due to several distinct. Universal embedded motor control the brushless direct current (bldc) motor is a type of a the thesis rst describes the theory behind the control algorithms that. The brushless dc (bldc) motor is becoming increasingly popular in sectors such as automotive (particularly electric vehicles (ev)), hvac, white goods and industrial because it does away with the mechanical commutator used in traditional motors, replacing it with an electronic device that improves.
