It depends on both the wiring of the motor and what if any residual magnetic field remains in the field windings. If there is some residual field, you will get some volts, but not many. If the motor has permanent magnets, it is effectively a dynamo.

How does ac electric motor convert in to an alternator?

a motor is a generator and a generator is a motor, if you are applying a voltage to turn the rotor its a motor and if you are turning the rotor and taking the voltage off the terminals its a generator or alternator.


Can you use a dc generator as a dc motor?

Yes you can turn a motor into a generator, if it is a permanent magnet motor.


Is it possible that you use motor as a generator input and electricity of the generator provide to a motor as a input?

If I'm understanding the question, you are proposing using one motor and one generator, and have the motor spin the generator up to speed, and have the generator attempt to supply power to the motor. The answer is yes, you can do this, but you will be losing energy, not gaining it. The motor and generator's efficiencies are less than 100%, so once you remove the outside source they will slow down until they come to a complete stope, without any other load connected other than themselves.


Difference between a generator and a motor?

A generator converts kinetic energy into electrical energy; a motor converts electrical energy into kinetic energy.


Can you use a dc series motor as a prime mover for a dc generator. if not why?

A DC series motor would be ill-suited to this application. There would be times when the generator would be only lightly loaded and would present only a small mechanical load to the motor. Under these conditions the current in the field winding of the motor would become smaller and it would turn faster to generate the counter EMF necessary to balance its supply voltage. This could result in damage to both the motor and the generator. Please see the link.

Some will have an electric motor. Others will have a place, usually in the rear of the camper that takes a crank handle that allows you to manually crank up the top.

If the motor doesn't work, there should be a way to manually crank it open or closed.


How does a battery help us?

A battery stores an electrical charge without the need for an active generator. Without a battery, in the context of automobiles, you would need to manually crank your engine to make it start. Manually cranking an engine takes a fair amount of effort, so an electrical starter motor is a very big help when starting a car.


How do you shut a Subaru Forester moon roof stuck open?

How is an electric motor different than an electromagnet generator?

Some types of motor can work equally well as a generator. A DC motor runs on a DC supply and supplies a mechanical load. If the load is removed the motor will free-run a little faster. But if the shaft is then driven faster than that, the current flows the opposite way and the motor has become a generator.


Why load angle is positive for generator and negative for motor?

simply put a motor consumes power and a generator produces it. reactance of a generator = - reactance of a motor


Can a motor operate as generator?

Yes, by giving mechanical power to motor . It acts as a Generator.
