Super Critical Speed Rotor Dynamics Advantage



Whenever possible we design our AC motors to operate below the first critical frequency. But the most demanding applications require us to push the limits, exceed the first critical frequency milestone and operate in a super‐critical speed range. A challenge and science that few understand and even fewer have experience in. We are able to achieve this modern engineering feat, though tedious FEA analysis, high speed rotor/shaft balancing equipment, and the unique insight that comes only through previous research and successes.
