WELMA-200 High-Speed Permanent Magnet Synchronous Motor and Generator


High-efficiency electric machine WELMA-200

Welma-200

Synchronous reversible type electric machine with excitation from high-coercivity permanent magnets. Capable to operate in both motor and generator modes. High torque throughout the entire load range. Designed to work as part of test bench equipment, compressor or micro-gas turbine unit, auxiliary propulsion units in aircraft and special vehicles. The product is controlled from the operator panel or via a digital communication channel (RS-485 ModBus RTU).


In generator configuration it has the following advantages:

  • can operate in two modes - starter and generator. In the starter mode the power generator is started in motor mode for pre-spinning the gas turbine engine. In this mode, the frequency inverter is powered by the external industrial power grid or a high-voltage electric battery. When switching to generator mode, the switch to power from the generator and generation of electricity of a given type and quality at the output of the product occur.
  • the power generation system can operate in island and parallel mode, providing electricity to an isolated facility, and in parallel with the facility's power supply, supplying excess energy to the power grid.

Technical parameters and dimensions of the product are adapted to the requirements of customer's technical specifications
