Synchronous Motors
Synchronous motors are like induction motors in that they both have stator windings that produce a rotating magnetic field. Unlike an induction motor, the synchronous motor is excited by an

Why Damper windings used in synchronous motors
Synchronous motors are not self starting machines. These machines are made self starting by providing a special winding in the rotor poles, known as damper winding or squirrel cage windings.
Applications of Synchronous Motors
For industrial squirrel cage induction motors are used mostly for the motor and drive systems applications. Synchronous motors are very rarely used below 40kW output because of the higher cost
Advantages & Disadvantages of Synchronous Motors
In industries induction motors are employed mostly because of less cost, rugged construction, good starting torques and very less maintenance. Synchronous motors are rarely used in industries for drive applications.
Voltage Variations Effects on Power Plant Equipment
When the voltage at the terminal of the electrical equipment deviates from the value as specified from the name plate the equipment performance and life time of the equipment are
Types of AC Motors and DC Motors
Electric motor is a machine which converts electric energy into mechanical energy. Its action is based on the principle that when a current-carrying conductor is placed in a magnetic field,
