Permanent magnet generator production for wind power

Who makes permanent magnet generators for wind turbines?

ABB has been developing and delivering permanent magnet generators for wind turbines since 2000, helping turbine manufacturers remain both on schedule and within budget. Leading wind turbine manufacturers trust ABB’s expertise, and today most of the megawatt-class permanent magnet generators operating in Europe and North America were built by ABB.

How can permanent magnet synchronous generators improve the performance of offshore wind turbines?

In order to install offshore wind turbines, the solution of a permanent magnet synchronous generator can lead to a high reliability and high performance system compared to other solutions on the market. To increase the attractiveness of this topology by reducing its cost and its weight, some design improvements can be made to the machine.

What is a switch permanent magnet generator?

As a pioneer, we challenged the wind industry first by making PMGs the preferred technology for offshore wind turbines and then making them commercially available to onshore turbines. The Switch permanent magnet generators increase annual energy production, minimize total life cycle costs, and fulfill the strictest grid code requirements.

What is a permanent magnet generator (PMG)?

Permanent magnet generators (PMGs) increase annual energy production (AEP), minimize total life cycle costs (TCLs) and fulfill the strictest grid code requirements. Together with a full-power converter, they enable high reliability, better overall efficiency and the ultimate future-proof grid code compliance.

What are the different types of permanent magnet generators?

The use of permanent magnet generators (PMGs) is gaining popularity also in wind power generation. In practice, there are three PM wind generator alternatives: 1) direct-drive (DD) generators (10 - 20 min-1), 2) medium-speed (MS) generators (100 - 300 min-1) and 3) high-speed (HS) generators (1000 - 2000 min-1).

Why do wind power machines use permanent magnets?

The use of permanent magnets offers freedom in machine design and the highest possible efficiencies for wind power machines. Although full power converters must be used with permanent magnet machines, these converters make it possible to fulfill even the strictest grid codes.
