Constant Current System for Speed Control of DC Motor: For certain services, where there is a possibility of the motors being stalled such as with excavators, ship's windlasses etc. the…
Booster Speed Control of DC Motor: A booster in series with the armature of the main motor may be employed for varying the voltage across the driving motor. The booster…
Armature Resistance Control Method of DC Motor: In this armature resistance control method of speed control, reduced speeds are obtained by inserting resistance in the armature circuit. It may be…
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…
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…
Starting and Speed Control of Single Phase AC Series Motor: The starting and speed control of single phase AC series motor is carried out by varying the applied voltage. As…
Thyristorised Control of DC Electric Traction Motor: The modern trend is towards the use of dc motors (both separately excited and dc series motors) equipped with thyristor chopper control. The…
