Capacitor-Start Capacitor-Run Single Phase Induction Motor: The capacitor-start capacitor-run motor is similar to capacitor-start, induction-run motor, except that the auxiliary winding and a capacitor remain connected in the circuit at…
Special Features of Thyristor Drive Motors: The most commonly used dc motors for thyristor drive are separately excited and series excited dc motors. The thyristor drive motors usually differ from…
Speed Control of DC Motor using Feedback Loop: An open-loop system can be converted into a closed-loop system by employing a speed control of dc motor using feedback loop, as…
Electric Braking of Separately Excited DC Motor: The electric braking of separately excited dc motor is show in Figure 3.31. Figure 3.31 (a) illustrates a simplified representation of a single…
Thyristor Control of 3 Phase Synchronous Motor: The synchronous motor is a constant speed motor and it develÂops torque only at synchronous speed which is directly proportional to supply frequency.…
Speed Control of Single Phase Induction Motor using Triac (Fan Regulator): The conventional speed regulator for a fan uses a resistance regulator. The regulator resistance is in series with the…
