The A10VM45EZ1/52W2-VWC60N000 variable motor is built by Bosch Rexroth as part of the A10VM Variable Motors series. It is intended for hydraulic automation where a variable displacement unit converts fluid energy into rotary motion. The motor delivers a maximum displacement of 45 cm³ per revolution, allowing output to match system demand. At this displacement the unit operates at a nominal speed of 4000 rpm and withstands a nominal pressure of 280 bar. Inlet flow reaches 180 l/min under these nominal conditions. Torque output is 200 Nm at 280 bar with displacement set to maximum. Electronic actuation uses a 12 V DC control signal, and the solenoid draws a nominal current of 1.5 A to shift the swashplate.
Performance limits include a maximum speed of 4600 rpm at minimum displacement and a continuous minimum speed of 250 rpm for low-flow operation. System pressure may rise to 350 bar, which defines the permitted maximum working value. The motor’s drive shaft carries a 7/8-inch 13-tooth 16/32DP spline, while a 1/4-20 UNC-2B thread is provided at the shaft end for accessories. Axial and radial forces are each limited to 1500 N to protect bearings. Fluid return uses a 7/8-14 UNF-2B drain port thread, and working ports secure to the circuit with a 3/8-16 UNC-2B fastening thread. These mechanical boundaries and threaded interfaces guide reliable installation within hydraulic drives.
