White Roller Stator Motor – 505375A5120AAAAA is a high-displacement RE 505 Series motor for fixed installations where the work is physically demanding and unrelenting — chippers, drum drives, heavy conveyor systems, and winch drives that run at sustained high torque without cycling down. On a 6-hole mount with a straight, keyed shaft, the motor stays locked in place and delivers 8,900 in-lbs of continuous torque directly into the driven equipment. Impro Fluidtek builds these motors on the original White Drive Products patents, acquired directly from Danfoss in 2022. This motor also replaces 500375A5120ZAAAA or 500375A3120AAAAA.
