Under what condition can an induction machine be operated as a generator?

synchronous speed
The Induction Motor becomes a generator when it is connected to an electrical power system and then driven above its synchronous speed by some prime mover.

How do you turn a 3 phase induction motor into a generator?

If you want an induction motor to self-excite as a generator you need to connect a sufficient capacitor across one or more of the windings then drive the motor at or above synchronous speed and it will self-excite and be ready to deliver power to loads.

What is the difference between induction motor and induction generator?

An induction generator looks a lot like an induction motor used in industry and it is, the difference is when the machine is rotated faster than its normal operating speed, an induction generator produces AC electricity.

Is induction generator self start generator?

An induction generator is not a self-excited machine. Therefore in order to develop the rotating magnetic field, it requires magnetizing current and reactive power.

Can motor act as a generator?

Yes. Practically any type of motor can also serve as a generator. A DC motor operated in reverse supplies current from the positive terminal. A synchronous motor (including permanent magnet (PM)) will produce power if run by an engine.

Can an induction motor be used as a generator?

Induction generators operate by mechanically turning their rotors faster than synchronous speed. A regular AC induction motor usually can be used as a generator, without any internal modifications. An induction generator usually draws its excitation power from an electrical grid.

Can a motor work as a generator?

You can use just about any motor to generate electric current, if it is wired correctly and you follow specific rules for its use. Modern AC induction motors are quite simple to wire as alternating current generators, and most will begin generating electricity the first time you use them.

What type of motor can be used as a generator?

brushless DC motors
Both brushed and brushless DC motors can be operated as generators.
