VTA MicroTurbine

The generator operates at the same speed as the turbine (up to 96,000 rpm) because the permanent magnet is located directly on its drive shaft. The high-frequency alternating current (1,600 Hz) generated in this way is rectified in the turbine''s power electronics and subsequently reversed to alternating current again (50 Hz / 400 V).

OverviewDesignMarketUltra microAircraftHybrid vehiclesExternal links

A microturbine (MT) is a small gas turbine with similar cycles and components to a heavy gas turbine. The MT power-to-weight ratio is better than a heavy gas turbine because the reduction of turbine diameters causes an increase in shaft rotational speed. Heavy gas turbine generators are too large and too expensive for distributed power applications, so MTs are developed for small-scale power like electrical power generation alone or as combined cooling, heating, and power (

Experimental Campaign Tests on Ultra Micro Gas
