White Roller Stator Motor – 505350A5120AAAAA is a high-displacement RE 505 Series fixed-installation motor for equipment that runs hard through sustained high-torque work cycles — chippers, drum drives, heavy feed systems, and winch drives where the motor delivers 8,150 in-lbs of continuous torque into the driven assembly without stopping. On a 6-hole SAE A mount with a straight keyed shaft, the drive connection stays positively locked through the load fluctuations that continuous heavy-duty operation produces. Impro Fluidtek builds these motors on the original White Drive Products patents, acquired directly from Danfoss in 2022. This motor also replaces 500350A5120ZAAAA or 500350A3120AAAAA.
