Maximum output phase-to-phase voltage is roughly equal input phase-to-phase voltage.
Industry standard 50/60 Hz induction motor can be operated at slightly higher frequencies in "field weaking" mode with reduced torque. Practically, up to double speed (1/4 of rated torque) may be reasonable in some cases.
The high inverter frequency range is only suitable for specially designed motors, e.g. aviation motor with 400 Hz rated frequency or small borehole pumps.
