RE: Normal Duty vs Heavy Duty Vfd ratings. LionelHutz (Electrical) 1 Jun 09 08:44. Lets consider 480VAC drives in North America. A 40hp drive would be rated 52A continuous and 110% or 57A for 1 minute. The manufacturer now wants a drive with the 150% for 1 minute rating so someone just calculates 57A / 1.5 = 38A.

Because of the lower overall efficiency of the hydraulics system, compared to VFD/Mechanical drive, a larger HP electric motor is generally required for hydraulics. If VFD drive requires 150HP, hydraulics would typically use 200 t0 250 HP motor for the power unit. The difference in HP requirements has an impact on power consumption.

Properly derate VFDs. Preventing faults and failures starts by right-sizing the VFD for the machine task. Single-phase input voltage on a VFD with 3-phase input is common in many automation applications. Depending on the horsepower and voltage rating, drives can accept single-phase input voltage without derating the output current.
