Medium-speed permanent magnet generators
Up to 10 MW, 100–600 rpm
Our medium-speed PMGs operate with a single- or two-stage gearbox. Combining the advantages of low- and high-speed technology, these PMGs offer extremely high availability and reliability, resulting in increased annual energy production.
FusionDrive®
The most compact medium-speed solution available on the market today, FusionDrive®, utilizes the same frame for both the generator and gearbox. FusionDrive® is the result of bringing together the world-class wind power technology of Moventas, one of the industry’s leading wind gear manufacturers, and The Switch.
All generator active parts are assembled directly around the secondary gear stage, so the generator and gearbox can utilize the same bearings. The gearbox lubrication oil can then be used to cool the generator. This solution is compact in size and offers the lowest weight in the market.
Advantages of permanent magnet generators
| High availability | Extremely high availability due to the simple and robust design. |
| Outstanding system efficiency | Superior efficiency over the entire wind speed range, even at partial loads, resulting in higher efficiency and increased AEP rates. |
| Optimal design | Optimized and tailored to each wind turbine and its operating environment. |
| Minimal maintenance | Fewer failures and significantly reduce maintenance needs due to highly serviceable design and minimal wearing parts. |
| Superior grid connection behavior | Future-proof grid code compliance, including fault-ride through and 100% reactive power compensation, when coupled with a full-power converter. |
