Yes. Greenheck supplies specific motors when the fan is to be used in conjunction with a VFD. Motor manufacturers differ on the type of motor they recommend when using a VFD, to insure that the motor and drive are compatible ask your drive supplier what motor characteristics they recommend for their drives.
