A permanent magnet alternator (also called PMA, permanent magnet generator, PMG or magneto) relies on the magnetic field generated by a permanent magnet to convert mechanical energy into electrical power. It can generate AC current, with which it can power the whole engine and charge the battery. A

Advantages: VAWTs offer a number of advantages over traditional horizontal-axis wind turbines (HAWTs). They can be packed closer together in wind farms, allowing more in a given space. This is not because they are smaller, but rather due to the slowing effect on the air that HAWTs have, forcing d

The excitation magnetic field of a PMG is generated by a permanent magnet, which is the main difference with the excitation generator. The permanent magnet is not only the magnetic source in the motor but also the component of the magnetic circuit. The performance of permanent magnets not only r

There are two different types of wind turbine system: 1. Off-grid system (Independent working) 2. On-grid system (Connected to the utility power) Off-grid wind power generator usually in small scale, and it can solve power supply problems in remote areas through energy storage dev

The first time you see a Nemoi wind turbine, you may not realize it’s a turbine at all. A white and silver metallic structure about the size of a garden shrub, Nemoi has three vertical blades that spin carousel-like around a central axis. The spinning is constant, but completely silent, and it doesn’t look fast enough to be generating much energy.
