White Roller Stator Motor – 505120W3120AAAAA is the smallest-displacement wheel drive motor in Empire's RE 505 Series lineup. Impro Fluidtek builds this motor on the original White Drive Products patent, acquired directly from Danfoss in 2022. It belongs on compact mobile equipment where the drivetrain uses a keyed or coupled interface at the wheel rather than a direct taper fit at the hub. With 121 cm³/rev displacement and 2,900 in-lbs continuous torque, it keeps small sweepers, compact utility vehicles, and light grounds maintenance equipment moving reliably through continuous propel duty. This motor also replaces 500120W3120ZAAAA.
