    I have a 4kw air compressor. 220v/380v rated

    I have wired the motor in delta. For 220v 3 phase.

    The Badge on the motor states RPM 2880 at 50 hz

    I have a 4kw VFD. Set at 50hz. This is giving me 1440 RPM. The single phase power input is 240V (France used to be 220v but is now 240v) . The VFD states it is drawing 5.2A

    Can I safely increase the HZ to bring up the Motor RPM ?
