White Roller Stator Motor – 505540W3120AEAAA is a high-displacement RE 505 Series wheel drive motor with an integral 1,500 psi relief valve. This motor powers equipment that moves loaded, over rough ground, without stopping. The 1,500 psi integral relief valve protects the motor during pressure spikes that come with that kind of work. Impro Fluidtek builds these motors on the original White Drive Products patents, acquired directly from Danfoss in 2022. 536 cm³/rev and 8,700 in-lbs continuous torque equip it to power large zero-turn mowers, road sweepers, and heavy duty skid steers operating in tight spaces: machinery that's mobile, heavy, and built to drive directly through the wheel without a separate gearbox absorbing shock.
