Synchronous Speed on Variable Frequency Supply: As has already been discussed, the speed of a synchronous motor can be varied by supply frequency variation similar to an induction motor. The…
Difference between Synchronous Sequential Circuits and Asynchronous Sequential Circuits: The difference between synchronous sequential circuits and asynchronous sequential circuits is given in table below Sl no Synchronous Sequential Circuits Asynchronous…
Speed Control of AC Commutator Motors: Speed control of ac commutator motors can be had either by varying the applied voltage or by movement of the brushes round the commutator.…
Speed Control of Single Phase Induction Motor: The stator winding of a speed control of single phase induction motor can easily be arranged to give two synchronous speeds, one double…
Speed Control of Three Phase Induction Motor: The problem of speed control of three phase induction motor in particular is of great practical importance. In a number of industries motors…
Starting of Synchronous Motor and Precautions: As already stated the synchronous motor has got no self starting torque and the motor must first be brought up to synchronous speed by…
Electric Motor Speed Torque Characteristics: A Electric motor speed torque characteristics is defined as the relationship between the speed at which it operates and the torque it develops, ω = f(T).…
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.…
