The AA10FM28/52W-VCC66N000 piston motor is built by Bosch Rexroth for the A10FM Piston Motors series. Designed for hydraulic automation, it converts pressurized fluid into consistent rotary motion. A geometric displacement of 28.5 cm³/rev defines the volume shifted per revolution, establishing flow requirements. At the nominal pressure of 280 bar it accepts an inlet flow of 134 L/min to reach its rated operating point. The unit produces a starting torque of 105 Nm at that same pressure, giving machinery adequate breakaway force. Its direction of rotation is alternating so circuits can command forward or reverse drive without redesign. Power is transferred through a tapered key with threaded bolt drive shaft that locks the connection against shock loads. Installation is handled by an ISO 3019-1 two-hole mounting flange, allowing direct replacement in standardized housings.
The motor withstands a maximum pressure of 350 bar for high demand cycles while delivering up to 62.5 kW of mechanical power at 280 bar. At full displacement it can rotate at 4700 rpm, and a maximum angular acceleration of 5500 rad/s² enables fast speed changes in servo-controlled systems. Continuous torque capability reaches 127 Nm at Vg max and 280 bar, balancing speed and load across the duty range. A case volume of 0.6 L captures internal leakage and aids heat dissipation. Fluid sealing relies on FKM material, giving chemical resistance to common hydraulic oils. Working ports follow ISO 11926 UN threads so hoses and adapters mate without modification. The assembled motor weighs 12 kg, a mass that fits typical mobile or stationary mounts while keeping structural loads moderate.
