What is the permanent magnet generator?

The 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. Permanent magnet generators are used mostly in industrial applications like turbines and engines to produce commercial electrical energy, the permanent magnet alternator is an alternate source of energy and has multiple benefits which make it a great device for a variety of residential, commercial, and industrial applications.

The structure

The permanent magnet generator is mainly composed of a rotor, end cover, and stator. The structure of the stator is very similar to that of an ordinary alternator. The biggest difference between the structure of the rotor and the alternator is that there are high-quality According to the position of the permanent magnet on the rotor, the permanent magnet generator is usually divided into a surface rotor structure and a built-in rotor structure.

Working Principle

The main components of permanent magnet generators are stators and rotors.

The rotor is made from permanent magnets, and it could generate magnetic fields. Magnetic parts are set around the stators as well, so fluxes could compass them.
The stator is composed of rotating coils. Once receiving the magnetic power, the stator generates electricity consequently.
In this way, the movement of the rotors is transformed into electric energy. The more stator coils we have, the more electric currents we get.

The permanent magnet alternator’s rotor is directly equipped with a wind turbine so that it can generate fixed electrical power. The efficiency of permanent magnet synchronous alternators is way higher than that of asynchronous generators. It offers a variety of merits over asynchronous generators and they are as follows:

· Direct drive (No speed multiplier, no gearbox needed)

· Virtually no maintenance

· Highest power-to-weight ratio in direct drive

· High efficiency

· Simplification of mechanical design · Easy mechanical interface

· Cost optimization

· They are environmentally friendly and do not rely on the external weather to produce electricity

· They are smaller in size and hence require very less space compared to other types of generators.

· These permanent magnet generators run for years and beyond without any wear and tear. Additionally, they are soundless and noise-free thus making zero sound pollution.

Applications of permanent magnet generators:

· Low-speed, direct-drive PMGs operate without any gearbox and fast-rotating parts, resulting in increased reliability and superior drive train efficiency.

· Generator can be designed with a segmented stator construction. This provides redundancy and makes it possible to repair the generator in the nacelle without full disassembly. Optionally, our generator design can use the generator bearing as a turbine main bearing to integrate the turbine brake system into the generator construction. Benefits are simplicity, fewer components, and therefore, higher reliability.

· With the rising cost of electricity, an increasing number of populations are looking for an alternate source of energy and permanent magnet generators fit this gap perfectly. These generators can also reduce the strain on the environment as they do not use any non-renewable sources of energy for producing electricity.

Benefits of Permanent Magnet Generators Over Induction Generators:

1. Free Energy Source

Permanent magnet generators produce electricity using their own magnetism. So, you do not need to pay high electric bills, and a large budget is saved. Besides, these devices do not need any other resources, which are quite environmentally friendly.

2. Reliable Power Output

Permanent magnet generators do not need any special operating environments. Hence, they can offer reliable performance compared with wind turbine motors. Additionally, permanent magnet generators do not suffer from energy loss, while induction generators typically lose 20-30% of energy. Additionally, there are no temperature rises in the magnetic machines, so the life of the bearings can be prolonged.

3. Low Maintenance Fee

Due to the features mentioned above, you do not need to spend lots of money and time on the maintenance of permanent magnet generators. And they do not have slip rings and brushes, which are supposed to be checked at regular intervals.

4. Compatibility

Permanent magnet generators can be employed with turbines and diesel generators.
