KM1 Orbital Hydraulic Motor for Drilling Head Drives | Low-Speed High-Torque Motor with Multiple Displacement and Mounting Options

1. Torque and Speed Matching for Drilling Head Drives

The KM1 orbital hydraulic motor series can be selected according to drilling-head load requirements, target speed, and hydraulic system specifications. With displacement options from 36 to 400 ml/r and a catalogue continuous torque range of 68–610 N·m, the series provides multiple configurations for hydraulic drive design. The selected model’s performance data must be checked to verify that its operating pressure and flow meet the application requirements.

2. Compact Design for Equipment Integration

The compact distribution shaft and integral rotor design help accommodate hydraulic drive layouts where installation space is a consideration. For drilling-head integration or motor replacement, engineers should verify flange dimensions, output-shaft specifications, and coupling requirements before ordering.

3. Multiple Mounting and Port Configurations

The KM1 series offers different output-shaft, mounting-flange, and hydraulic-port configurations. OEMs and maintenance teams can select a suitable combination according to the equipment structure and hydraulic connections. Confirm the required configuration using the manufacturer’s dimensional drawings and ordering codes.

4. Application-Based Selection for Operating Conditions

Drilling equipment may involve starting resistance, changing loads, and extended operating cycles. Motor selection should account for continuous pressure, flow rate, rotational speed, return-line back pressure, oil temperature, and external shaft loads. Matching the motor to the hydraulic system helps address potential issues related to insufficient output, unsuitable speed, or incompatible mounting interfaces.
