What is the difference between asynchronous motor and a synchronous generator




















For now, let us discuss the difference between synchronous generator and induction generator. Difference between synchronous generator and induction generator In a synchronous generator, the waveform of generated voltage is synchronized with directly corresponds to the rotor speed.

In case of inductions generators, the output voltage frequency is regulated by the power system to which the induction generator is connected.

Separate DC excitation system is required in an alternator synchronous generator. Induction generator takes reactive power from the power system for field excitation.

If an induction generator is meant to supply a standalone load, a capacitor bank needs to be connected to supply reactive power. Difference Between Synchronous and Asynchronous Motor are explained below in the tabulated form. Synchronous motor is a motor that operates at synchronous speed, i.

Asynchronous motor is an AC Induction motor. The rotor of the Asynchronous motor rotates at the speed less than the synchronous speed, i. This is because the rotor is held electromagnetically in rigid synchronism with the rotating voltage in the stator magnetic locking if you increase the load, the motor will draw more current armature wingdings so synchronous speed is maintained.

It may slow a little while it adjusts but only momentarily. However under certain conditions i. Very helpful, thank you! Is it correct to say that slip ring and squirrel cage induction motors, belong only to asynchronous motor? Your email address will not be published.

Skip to content The Difference Between Synchronous and Asynchronous Motor are explained considering factors like its type, slip, requirement of additional power source, requirement of slip ring and brushes, their cost, efficiency, power factor, current supply, speed, self starting, effect in torque because of change in voltage, their operational speed and various applications of both Synchronous and Asynchronous motor.

Difference Between Synchronous and Asynchronous Motor Synchronous motor is a machine whose rotor speed and the speed of the stator magnetic field is equal. Asynchronous motor is a machine whose rotor rotates at the speed less than the synchronous speed. If the RPM is held constant, the frequency varies depending on the power level. The peaks of the waveform have no fixed relationship with the rotor position.

An asynchronous generator is essentially the same machine as an asynchronous or induction motor. The magnetic field of the rotor is supplied by the stator through electromagnetic induction. The output frequency of a synchronous generator can be more easily regulated to remain at a constant value. Synchronous generators large ones at least are more efficient than asynchronous generators.

Synchronous generators can more easily accommodate load power factor variations. Synchronous generators can be started by supplying the rotor field excitation from a battery. Permanent magnet synchronous generators require no rotor field excitation.

The construction of asynchronous generators is less complicated than the construction of synchronous generators. Asynchronous generators require no brushes and thus no brush maintenance.

Asynchronous generators require relatively complicated electronic controllers. They are usually not started without an energized connection to an electric power grid, unless they are designed to work with a battery bank energy storage system. With an asynchronous generator and an electronic controller, the speed of the generator can be allowed to vary with the speed of the wind.

The cost and performance of such a system is generally more attractive than the alternative systems using a synchronous generator. A diagram of asychronous motor convert to generator. HomePage BookMark.
