What Does a Permanent Magnet Generator Do? Permanent magnet generators use magnetic force to generate electricity in conjunction with some form of mechanical movement, normally wind power. The primary benefit of a permanent magnet generator is that because there is no need for brushes which improves the reliability of the drive train.

en.wikipedia.org/wiki/Permanent_magnet_synchronous_generator

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.

Permanent Magnet Generators are Highly Durable. As permanent magnet generators do not require a battery to work, these are ideal for homes which are located in remote regions where it is hard to gather spare parts and find qualified mechanics. Also, permanent magnet generators do not require additional current for the excitation circuit.

What is a Permanent Magnet Generator? A permanent magnet generator is a device that converts mechanical energy to electrical energy. In this device the rotor windings have been replaced with permanent magnets. These devices do not require a separate DC supply for the excitation circuit or do they have slip rings and contact brushes.

Assuming the question implies some sort of perpetual motion machine then the answer is quite simple when considering that the Total Energy of a System = potential energy (PE) + kinetic energy (KE). Therefore a magnet has 100% PE, but when the PE b...

Permanent magnet generators produce electricity by rotating strong magnets around metal wires. These conductive wires then convey the electricity throughout a residence or industrial complex for decades, because the magnets do not have to be replaced for up to 25 years.

Electric generator - Permanent-magnet generators: For some applications, the magnetic field of the generator may be provided by permanent magnets. The rotor structure can consist of a ring of magnetic iron with magnets mounted on its surface. A magnet material such as neodymium-boron-iron or samarium-cobalt can provide a magnetic flux density in the air gap comparable to that produced with ...

A wind electric generator uses induction and permanent-magnet designs. There are many variations of these two, but in general terms, the induction generator must be spun at about 1,000 rpm or more to produce useful power. It produces current by first generating an electric field by passing alternating current (ac) through a coil.

The magnetic field is established by using a magnet. You can use different types of magnets – it may be an electromagnet or it can be a permanent magnet. A Permanent Magnet DC motor (or PMDC motor) is a type of DC motor that uses a permanent magnet to create the magnetic field required for the operation of a DC motor.
