Generators for hydropower applications - with high efficiency

AXCO-Motors’ permanent magnet generators are perfect choices for hydropower turbine applications. Product range covers conventional vertical and horizontal machines as well as submerged units (bulb turbines or similar). Our engineers help you choose the most suitable design for your hydropower project to fit units to the working environment. AXCO-Motors' hydropower generators are based on permanent magnet radial flux technology. They can be easily adapted to existing powerhouse buildings. The generator structure provides good performance and high efficiency. The phase voltage and current are purely sinusoidal, and torque ripple is low.

Unique qualities:

Efficiency: no mechanical drive losses
Reliability: no gearbox needed, power electronic components kept in minimum
Versatility: the generator can be designed to fit in old building and structures
Environment: oil-free system, no gearbox
Cost efficiency: permanent magnet direct-on-line generator is a perfect match especially for low head (H < 50m) power plants and low speed Kaplan turbines

Our generators are tailored to match your company’s needs and challenging conditions. The high efficient design of generators maximizes the energy production. These qualities give you an edge in competitive business environment!

Synchronizing opportunities for grid

Direct-On-Line (DOL) connected, pure PMG or Hybrid PMG allowing cosphi regulation

Direct-On-Line (DOL) connected with parallel running reactive power compensation system

Line converter (full power converter) connected

The direct-connected solution is simple, thus reducing the investment needed, as well as eliminating the fault possibilities in power electronics. On the other hand, the line converter version enables power supply in variable power situations. Often, a system of multiple generators can be built by using one power converter unit and some three to four directly connected units. We use only highly reputed converter brands in the system deliveries. The power converter can be included in AXCO-Motors’ scope of supply, or excluded. In the latter case, we will assist in specifying the applicable components. The system comes also with technical support in design and commissioning.
