Areas of Application

Auxiliary Power Unit (APU).

Uses a three-phase synchronous generator to save fuel by shutting down the vehicle's main diesel engine during stops. A separate small diesel engine for the on-board network supplies power to the generator and air conditioning compressor when stationary. This avoids high no-load losses.

Three-phase synchronous generators ensure a reliable energy supply for the on-board networks of trains, cable cars and other vehicles in stationary operation.

Three-phase synchronous generators in hydroelectric power generation.

Permanent magnet generators (PMGs) operate over a very wide speed range and supply power to the inverter.

Synchronous generators are very efficient, especially in extensive part-load operation.

Even with low water flows, the generator is driven and feeds power into the grid via the inverter.

The user's financial revenue (feed-in tariff payments) is maximized and the higher initial costs are amortized more quickly.

Three-phase synchronous generators in wind power production.

Maximum efficiency of the generator is designed with the available turbine characteristics and power using the measured characteristic data of the generator.

Low starting torque even at low wind speeds.

Optimal energy output by generating energy over a wide speed range.
