AA10FM45/52W-VWC66N000

The AA10FM45/52W-VWC66N000 motor belongs to the A10FM Piston Motors series and is produced by Bosch Rexroth for closed-loop hydraulic drives. It converts hydraulic energy into mechanical rotation for automated machinery. A geometric displacement of 44.5 cm³ per revolution defines the volume of fluid needed to complete one shaft rotation, providing predictable flow calculations. At its nominal speed of 4000 rpm the inlet flow reaches 178 L/min, matching high-demand circuits where compact size and high throughput are required. The unit is rated for a nominal pressure of 280 bar and can tolerate a maximum pressure of 350 bar, so system designers can operate safely at working pressure while retaining overload capacity. Under the 280 bar working point it delivers 198 N·m of torque and 83.1 kW of mechanical power, giving precise figures for sizing gear reducers or coupling elements. The direction of rotation is alternating, allowing the same housing to handle clockwise and counter-clockwise flow without modification. An ISO 3019-1 two-hole mounting flange standardizes installation on common pump/motor pads, simplifying interchangeability.

The dynamic characteristics further clarify integration tasks. A moment of inertia of 0.0033 kg·m² limits stored kinetic energy, permitting rapid speed changes with modest drive effort, while a maximum angular acceleration of 4000 rad/s² sets a ceiling for command profiles in servo-controlled loops. The shaft terminates in a 7/8-inch, 13-tooth, 16/32DP spline that provides positive torque transmission to gearboxes or pulleys. Hydraulic connections follow industry threads; the working port uses a 1 1/16-12 UN-2B thread and the drain port is cut to 7/8-14 UNF-2B, enabling direct hose fittings without adapters. FKM seal material resists high temperature and aggressive hydraulic fluids, extending service life in demanding environments. Overall weight is 17 kg, light enough for one-person handling during maintenance yet substantial for vibration damping. These mechanical, hydraulic, and material parameters together define how the motor responds in automated hydraulic circuits.
