The AA2FM63/61W-VTD510 belongs to the A2FM Fixed Motors series and is manufactured by Bosch Rexroth for hydraulic automation tasks that require consistent displacement. Its operating principle is an axial piston bent-axis design, converting pressurized fluid into rotation with a compact internal geometry. The displacement is 63 cm³ per revolution, defining how much fluid moves through the unit during each shaft cycle. A torque constant of 1.00 Nm per bar links system pressure directly to output torque. At 400 bar the shaft produces 400 Nm, supplying substantial force in a small package. The nominal pressure rating is 400 bar for continuous duty, and the motor withstands up to 450 bar during short pressure spikes.
The unit sustains 5000 rpm for regular operation, supporting high-speed drive requirements, and it accepts 5500 rpm intermittently for short acceleration phases. Reaching top speed draws an inlet flow of 315 L/min, a figure that assists in sizing pumps and lines. Housing pressure must stay below 10 bar absolute to protect internal components from cavitation. A 4-hole ISO 3019-2 mounting flange connects the motor to standardized machinery interfaces. Bidirectional rotation allows clockwise and counter-clockwise drive without mechanical changes, simplifying circuit layouts. FKM sealing material endures hot hydraulic oil and maintains leak-free operation over extended service intervals.
