White Roller Stator Motor – 505540W3120AAAAA is a high-displacement RE 505 Series wheel drive motor built for heavy mobile equipment running slow and loaded — equipment that moves under sustained traction demand where the system design manages overpressure protection separately and no integral relief valve is required at the motor. On a 4-hole wheel mount with a straight shaft, it connects to the driven assembly through a coupled interface and delivers 8,700 in-lbs of continuous torque to large agricultural machines, heavy material handlers, and construction equipment through continuous propel duty. Impro Fluidtek builds these motors on the original White Drive Products patents, acquired directly from Danfoss in 2022. This motor also replaces 500540W3120CAAAA.
