axpert eazy hf drive power ratings from 1. 5kw to 37kw are available. Our drives are suited for very wide range of ac motors (induction or permanent magnet ac), from low speed (rated 50 or 60 hz) through very high speed (rated up to 1800 hz).
we have a special experience in the application of high speed machining spindles, reduction of their vibration and in the reduction of heat inside high speed motors in general. The series axpert eazy hf drive digital inverter incorporates a proprietary pwm sinusoidal waveform designed especially to operate motors and spindles running at extremely high speeds. Our improved pwm technology and igbt devices result in a more perfect sine wave free of harmonics and without dc current which can increase bearing & insulation life of high speed spindles.
