KM1 Series Orbital Hydraulic Motor

1. Compact Design and High Power Density

The KM1 series orbital hydraulic motor features a compact distribution shaft and an integral rotor design. Its compact construction and high power density make it suitable for hydraulic equipment where installation space and drive requirements need to be balanced.

Multiple flange, output shaft, and oil port configurations are available. These options help equipment manufacturers evaluate the motor for different mounting arrangements and hydraulic system layouts.

2. Displacement Options for Different Drive Requirements

With displacement options ranging from 36 to 400 ml/r, the KM1 series supports hydraulic motor selection across different flow, speed, and torque requirements.

The catalogue lists continuous speeds from 150 to 800 RPM across the available displacement specifications. Actual output depends on the selected displacement, flow rate, pressure differential, and mechanical load.

For accurate selection, compare the motor's continuous operating requirements with the equipment's actual duty cycle instead of relying solely on the maximum catalogue values.

3. Reversible Operation and Circuit Flexibility

The KM1 motor is designed for convenient forward and reverse operation and is compatible with series and parallel hydraulic circuits. Its shaft seal is designed to withstand elevated back pressure, subject to the allowable limits of the selected configuration.

When integrating the motor into an existing hydraulic system, check the return-line pressure, drainage arrangement, shaft connection, and port configuration. Appropriate hydraulic oil and operating temperature control are also important considerations.

4. How to Select the Right KM1 Hydraulic Motor

The KM1 series is intended for medium-duty hydraulic applications. It is worth considering when equipment requires a compact motor with multiple displacement and installation options.

Before placing an order, confirm the required displacement, continuous torque, rotational speed, flow rate, working pressure, shaft loads, mounting flange, and oil port connections. The catalogue specifies a maximum oil temperature of 80°C and a recommended anti-wear hydraulic oil viscosity of 37–73 cSt.
