Speed Control Of Separated Excited Dc Motor - very valuable
Lost password? The rotor needs to be rotated at a speed near to the synchronous speed during starting. It is more suited for constant torque and constant speed drives. However, with the invention of solid-state devices, the frequency of the current fed to the synchronous motor can be varied. I liked its essence and enjoyed reading it.

A separately excited d. A single-phase half-controlled rectifier is driving a separately excited dc motor. The dc motor has a back emf constant of 0. The armature current is 5 A without any ripple. The armature resistance is 2 Ohm. The converter is working from a V, single-phase ac source with a firing angle of 30o. A DC chopper is used for regenerative braking of a separately excited DC motor. The DC supply voltage is V. The armature current during regenerative braking is kept constant at A with negligible ripple.

If the load of the normally excited synchronous motor is increased the power factor will? If the load of the normally excited synchronous motor is increased the power factor will become lagging. If the field of synchronous motor is under excited, power factor will be lagging. Increasing current means increasing frequency of the motor because current is directly proportional to rotations of the motor rotor.
