Permanent magnet generators are synchronous machines with rotor windings replaced by permanent magnets. They need no separate excitation so rotor excitation losses – about 30% of total conventional generator losses – are eliminated. This results in high power density and small size with the highest efficiency at all speeds, offering the maximum annual production of energy with the lowest lifetime cost. ABB has a strong experience in permanent magnet solutions ensuring a reliable solution. • Premium efficiency at all turbine speeds • Proven reliability with maximized energy yield • Low cost of ownership in all aspects from purchase to downtime and maintenance • Short circuit withstand without demagnetization • Rotor with high overspeed endurance • Bearing design avoiding circulating currents • Compact size In full converter (FC) concept, using standard high speed drivetrain with permanent magnet generators, enables the smallest size and highest efficiency at all speeds. • Wind turbine proven High speed permanent magnet generator family available for other Renewable applications • Easy upgrade for doubly-fed turbine OEMs to the full converter concept • Robust PM generators offer the smallest possible size and weight • High efficiencies, also in partial load, reaching up to 98% • Grid code compliance and all the benefits of the full converter concept
