White Roller Stator Motor – 505470A5120AAAAA is a high-displacement RE 505 Series motor built for fixed-installation drives where the work is continuous, the loads are high, and the motor rarely rests. On a 6-hole mount with a straight keyed shaft, it stays in place and puts 9,700 in-lbs of continuous torque directly into the driven equipment — the chipper drum, the winch drum, the feed roller — without a wheel between the motor and the work. Impro Fluidtek builds these motors on the original White Drive Products patents, acquired directly from Danfoss in 2022. With 465 cm³/rev displacement running at 160 RPM continuous, this motor powers wood chippers and brush processing equipment, forestry winches and grapple head systems, and heavy industrial conveyor drives. This motor also replaces 500470A5120ZAAAA or 500470A3120AAAAA.
