Design Features and Key Advantages

The KMV Series cycloidal hydraulic motor features a fixed-rotor design and an advanced fluid distribution structure, combining low-speed, high-torque output with efficient operation. Its design supports high operating pressure and output torque, while the automatic compensation distribution structure helps accommodate hydraulic drive requirements.

The KMV range also includes wheel motor and brake motor configurations to suit different equipment layouts, drive systems, and braking requirements. The compact wheel motor design is particularly suitable for vehicle drive systems with limited installation space and demanding low-speed torque requirements.

Performance Parameters and Selection Guide

The KMV Series offers displacement options from 315 to 1000 ml/r to accommodate different speed, flow, and torque requirements. According to the catalogue, continuous torque ranges from 920 to 2015 N·m, with a continuous pressure rating of 21 MPa and an intermittent pressure rating of 25 MPa.

When selecting a motor, consider the following factors:

• Displacement: Match the motor displacement to the target output speed and available hydraulic flow.

• Torque requirements: Evaluate both continuous operating loads and starting loads, distinguishing continuous torque from intermittent torque.

• Hydraulic pressure: Verify that continuous system pressure and short-duration pressure peaks remain within the limits of the selected model.

• Speed and flow: Do not assume that maximum speed, maximum pressure, and maximum flow can be achieved simultaneously.

The catalogue specifies different performance values for different displacements. Final selection should be based on the actual operating conditions and the performance data for the chosen model.

Applications and Configuration Options

The KMV Series is available in standard motor, wheel motor, and brake motor configurations to meet different hydraulic drive requirements.

• Wheel drive systems: The wheel motor features a compact design for vehicle applications requiring low-speed, high-torque output.

• Low-speed, high-torque drives: Select the appropriate displacement according to load requirements, target speed, and available hydraulic flow.

• Drive systems requiring braking: The brake series specifies a brake release pressure of 20–35 bar and a braking torque of up to 900 N·m or less.

• Space-constrained equipment: Confirm installation dimensions, output shaft type, flange, and port connections before ordering.

Before placing an order, provide the equipment type, mounting dimensions, required output torque, operating speed range, and hydraulic system parameters to help identify a suitable configuration.

Ordering Checklist and Technical Support

To ensure that the KMV hydraulic motor matches your equipment, confirm the following details before requesting a quotation or placing an order:

1. Displacement: 315, 400, 500, 630, 800, or 1000 ml/r.

2. Motor configuration: Standard, wheel motor, or brake motor.

3. Mechanical interfaces: Output shaft type, mounting flange, mounting dimensions, and connection arrangement.

4. Hydraulic operating conditions: System flow, continuous pressure, intermittent pressure, target speed, and load torque.

5. Braking requirements: For brake motor configurations, confirm the required brake release pressure and braking torque.

Providing complete application and interface details helps reduce the risk of model incompatibility and supports a more accurate selection for your operating conditions.
