A permanent magnet synchronous generator is a generator where the excitation field is provided by a permanent magnet instead of a coil. The term synchronous refers here to the fact that the rotor and magnetic field rotate with the same speed, because the magnetic field is generated through a shaft-mounted permanent magnet mechanism, and current is induced into the stationary armature.
By the late 1980s, developments in magnetic materials such as samarium–cobalt, an early rare-earth type, let permanent magnet alternators be used in applications that require an extremely robust generator. In guided missiles, such generators can replace a flux switching alternator. [15]
Home experts explain how to buy the best home generator, including cost, size, portable versus standby home generator, and more, to prepare for a power outage.
It’s also important to consider that while generators are certainly a hefty investment, they will pass the test of time. Most home standby generators can run anywhere from 10,000 to 30,000 hours.
"Dynamo Electric Machine" (end view, partly section, U.S. patent 284,110) A dynamo is an electrical generator that creates direct current using a commutator.Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were based, including the electric motor, the alternating-current ...
Permanent magnet machines avoid the loss due to magnetizing current in the rotor, but are restricted in size due to the cost of the magnet material. Since the permanent magnet field is constant, the terminal voltage varies directly with the speed of the generator. Brushless AC generators are usually larger than those used in automotive ...
