ROTOR(SYNCRONOUS MACHINES)
Principle of Operation
The operation of a synchronous generator is based on Faraday's law of electromagnetic induction, and in an ac synchronous generator the generation of emf's is by relative motion of conductors and magnetic flux.
These machines can be used as either motors or generators but their predominant use is in generation.
ROTROTOR CONSTRUCTION:
The rotor is the rotating part of the electromagnetic circuit. The most common type of rotor is the "squirrel cage" rotor. Other. The construction of the squirrel cage rotor is reminiscent of rotating exercise wheels found in cages of pet rodents
Power and torque in synchronous generators
A synchronous generator needs to be connected to a prime mover whose speed is reasonably constant (to ensure constant frequency of the generated voltage) for various loads.
