400Hz Rotary Frequency Converter

Compact design because of the monoshaft arrangement – no alignment of the whole machine is necessary. The total length of the machine-set can be reduced up to 50% resulting also in lower weight. Air inflow and outflow ducts are possible The power factor of the motor is automatically controlled from 0.9 to 1.0 at 50% to 100% of nominal load. Higher efficiency because of just 1 fan, 1 exciter machine and 2 bearings No wear parts like clutch or brushes, just 2 bearings instead of 4 Higher MTBF-value (meantime between failure): more than 50 000 hrs. of monoshaft converter. Instead of one rotating start up resistor a reliable and roust starter winding is used. Patented exciter system Maintenance friendly through parts are easy of access.
