KM1 Series Compact Orbital Hydraulic Motor, 36–400 ml/r, Reversible Drive for Hydraulic Wrist Applications

1.Compact Design for Space-Constrained Installations

The KM1 Series orbital hydraulic motor features a compact distribution shaft and integral rotor design, offering a space-conscious drive solution for equipment with limited installation room.

For hydraulic wrist applications, verify the motor envelope dimensions, mounting flange, output shaft configuration, and port orientation to ensure compatibility with the wrist mechanism and hydraulic circuit.

2.Reversible Operation for Bidirectional Drive

The KM1 Series supports clockwise and counterclockwise rotation, making it a candidate for hydraulic mechanisms requiring bidirectional movement.

For hydraulic wrist rotation or positioning, select the motor according to the required movement direction, load conditions, and control valve arrangement.

According to the catalog, when viewed from the output shaft end, the motor rotates clockwise when oil enters Port A. Confirm the actual port connections against the equipment layout and hydraulic circuit design.

3.Multiple Displacement Options for Torque and Speed Matching

The KM1 Series is available in multiple displacement options from 36 to 400 ml/r. The catalog provides performance data for speed, pressure, and torque across different displacements.

For hydraulic wrist applications, determine the required output torque and rotational speed first, then verify the selected model against available flow, system pressure, and permitted intermittent operating conditions.

The catalog recommends operating within approximately one-third to two-thirds of the continuous operating conditions for an optimal working range. It also advises against operating at maximum speed and maximum pressure simultaneously.

4.Flexible Mounting and Connection Configurations

The KM1 Series offers multiple output shaft, mounting flange, and oil port connection configurations. It can also be used in series or parallel hydraulic circuits, allowing engineers to select configurations that suit their equipment layout.

For hydraulic wrist manufacturers and replacement-part buyers, provide the mounting drawing, shaft requirements, port locations, operating pressure, flow rate, and load conditions when requesting a quotation. Verifying both mechanical interfaces and operating parameters helps identify a suitable motor configuration and reduce installation compatibility risks.
