How Fast Can My Inverter Drive My Motor? This is a frequently asked question and the answer needs careful consideration. There are power and mechanical limits with a nod to the torque characteristics of a squirrel cage motor. The inverter itself is usually capable of providing the increased frequency. ABB inverters typically output 400Hz – 8 times the mains frequency! We will explore what to consider when assessing whether a speed increase of an existing…
