Danfoss OMT EM 200 151B3261 orbital hydraulic motor

Danfoss OMT EM 200, part number 151B3261, is a fixed-displacement orbital hydraulic motor with 201.4 cm³/rev geometric displacement. This execution provides integrated em speed sensor for rotational-speed monitoring.

The motor has a 40 mm cylindrical keyed output shaft, a 125 mm locating pilot and a 160 mm mounting bolt circle. Main ports are 3/4" BSP; the drain connection is 1/4" BSP. The shaft, flange and ports must match the mating installation.

The EM execution includes a PNP speed sensor. The European standard execution uses a Binder Series 713 plug connection. The selected original pages give electrical specifications, wiring and the size-specific EM mounting envelope. The current factory article identifies the exact part number; the technical reference retains the original manufacturer edition.

Select the operating point from the applicable size performance diagram and observe shaft-load, drain-line and shaft-seal pressure limits. Continuous, intermittent and peak limits describe separate duties. They must not be combined into one simultaneous maximum-duty point, and differential pressure is distinct from maximum inlet pressure.
