Can a permanent magnet motor be used as a generator?

Can a permanent magnet motor be used as a generator?

Permanent magnet direct current (DC) machines can be used as either conventional motors or as DC wind turbine generators as constructionally there is no basic difference between the two.

Is there a permanent magnet in alternator?

The excitation of the permanent magnet alternator or inductor is made by permanent magnets bonded to the rotor.

Why do alternators not use permanent magnets?

The rotor field strength required in alternators can be well generated by permanent magnets. A simple and sufficient reason why PMSG isn’t used for alternators is lack of the simple voltage regulation feature, it would need an additional high power switch mode converter.

How fast does a car alternator need to spin to produce power?

An alternator has a normal range of operation. Most alternators need to spin at about 2,400 rpm at idle, have their maximum output above 6,000 rpm, and should never exceed 18,000 rpm.

Is a permanent magnet generator AC or DC?

The PMG can be a DC voltage machine with brushes and rotary collector or much more frequently an AC synchronous multiphase machine whereas the stator and rotor magnetic fields are rotating at the same speed.

What is the minimum RPM of a 12v car alternator?

As was stated before, most alternators prefer a minimum speed of 2,400 rpm.

Is permanent magnet generator AC or DC?

What kind of magnets do alternators use?

Permanent Magnet Alternator with Neodymium Magnet Rotor.

How much power can an alternator produce?

But nowadays, a single alternator can produce power up to 2500 Watt, depending on the power demand. The power that can be produced by an alternator is determined by the alternator rating. The output of the alternator ranges from 40 Amp up to 120 Amp. For high-amp alternator, it can generate up to 300 Amp.
