Chapter 7 Synchronous Generators Pdf Electric Motor Force 1. the document describes the construction and operation of a synchronous generator. 2. it explains that the stator is made of laminated steel and contains slots for winding coils. the rotor contains field windings and rotates at synchronous speed. 3. synchronous generators work by inducing alternating current in the stator windings via the rotating magnetic field from the rotor field windings. Synchronous motors run in synchronism with the revolving field: when the frequency is fixed, the motor speed stays constant irrespective of the load or voltage of the 3 phase line.
Synchronous Generators Pdf Inductance Electric Power 7.1 introduction a synchronous machine can be used as a generator as well as motor without change in construction. the synchronous motor has same construction as alternator which was discussed in last unit section 6.2. in this unit, we will turn our attention to the working principle and starting methods of synchronous motor. in three phase system, induction and synchronous motors are used. so. Synchronous machines: synchronous machines are ac machines that a field circuit supplied by an external dc source synchronous generators or alternators are synchronous machines used to convert mechanical energy into electrical energy. synchronous motors convert electrical energy into mechanical energy. The power source for this type of system is a potential and or a current transformer supplied by the synchronous generator terminals. three phase power is fed to a rectifier, and the rectified dc output is applied to the synchronous generator field via slip rings and brushes. Synchronous machine modeling electric machines are used to convert mechanical energy into electrical energy (generators) and from electrical energy into mechanical energy (motors) many devices can operate in either mode, but are usually customized for one or the other.

An unloaded synchronous machine is called synchronous condenser and is used to improve the power factor of the system. example 2 : a 3 , 10 kva, 400 v, 4 pole, 50 hz star connected synchronous machine has synchronous reactance of 16 and negligible resistance. Summary synchronous machines are principally used as alternating current (ac) generators. they supply the electric power used by all sectors of modern societies: industrial, commercial, agricultural, and domestic. synchronous machines are sometimes used as constant speed motors, or as compensators for reactive power control in large power systems.
