Bosch Rexroth A6VE107EP1/63W-VZL027FPB-SK axial piston variable plug-in motor

A6VE107EP1/63W-VZL027FPB-SK, material number R902182410, is a factory-listed A6VE107 variable plug-in motor for hydrostatic drives. Its bent-axis rotary group is designed for integration into a mechanical gearbox. The EP1 proportional electric control uses a 12 VDC nominal solenoid supply and reduces displacement as control current increases.

The dated manufacturer RE91606/06.12 reference gives a base-motor geometric maximum of 107 cm³/rev, nominal working pressure 400 bar absolute and peak 450 bar absolute for single periods up to 10 seconds with 300 hours cumulative exposure. The 3550 rpm limit at maximum displacement and 5600 rpm limit below 68 cm³/rev require mineral oil in the optimum 16–36 mm²/s viscosity range, permissible inlet flow and applicable radial-load limits. These are qualified base-motor series limits, not an unconditional rating for fitted valves or a customized assembly. The supplied minimum displacement and control settings are not established by the published record.

Use the actual factory designation when confirming installation. The 020/027 standard port family uses lateral, opposing SAE working ports; the 027 code references a flushing and boost-pressure valve, whose exact orifice and settings are not inferred. Exact suffix-specific accessories and stop settings require the manufacturer’s binding installation drawing. The technical reference is the manufacturer’s June 2012 series edition; exact control settings and accessory limits must be checked for the supplied execution.

The manufacturer series photograph is representative and may show different control equipment from this execution.

The mineral-oil base-motor reference requires at least 25 bar absolute on the high-pressure side and limits the sum of pressures at A and B to 700 bar. During pump-mode braking, the inlet-pressure requirement also depends on speed and displacement as shown in the original curve.
