Drive Overview
The FUJI ELECTRIC FRN5.5VG7S-4 is a variable torque drive, designed for loads where torque demand rises with speed — typical of centrifugal pumps and fans in HVAC, water treatment, and process lines. The variable torque profile means the drive is sized for the lower starting torque of these loads, so it runs the motor efficiently across the speed range without oversizing the drive chassis.
