ETS AC CONVERSION PACK DC ENERGY CONSUMPTION vs EXTRUDER SPEED NORMALIZED vs AC DRIVE SYSTEM In operating range, a 100 RPM, DC system consumes 5 to 15% MORE power than an AC system. This chart details the results of AC and DC motor trials in our Davis-Standard technical center. Trials were run on a 2 1/2-inch (64 mm) 30:1 smooth bore extruder. The DC and AC motors and drives were installed on the 2 1/2-inch machine. The same extrusion screw timing was used to run HDPE 0.3 MI and PP 20 MFR materials. A fluke power analyzer was used to record and capture the power data. EXTRUSION ETS TECHNICAL...
