Welcome to CR4, but there is not much information here to work on (in future please provide as much information as possible to assist those trying to figure out what you want).

Given the simple question, the simple answer is that it depends on the VFD. Many modern VFDs (Variable Frequency Drives) are more than capable of running standard three-phase motors without the need for more expensive VFD-rated motors (although care is needed to shield and filter the motor output and/or input (refer to VFD manual)), specifically the motor winding insulation is better to handle voltage spikes that cheaper VFDs produce.

If in doubt, check with your VFD supplier (or data sheets) to ensure that your application and VFDs are suitable for use with standard motors before buying VFD-rated motors.

Was this what you were after?
