Hi,
three phase motors that are made for running off a VFD are called 'inverter ready' and attract a significant premium.
Most ordinary three phase motors work fine but the VFD introduces high frequency currents which result in very high (local) voltages within the windings
which can result as a flash-over. Inverter ready motors often have vacuum impregnated windings and increased insulation thickness to accommodate those voltages.
Most rotors will accommodate running a bit faster than rated speed, but you might be pushing the envelope at 4500 rpm, remember that the centrifugal forces go up
as the square of speed so: (4500/2800)2=2.6 times the force.
