Key Features and Technical Specifications

Selecting the right hydraulic motor involves evaluating several critical performance parameters. These specifications determine how well the motor integrates with your hydraulic system and performs under real-world operating conditions. Below is a detailed breakdown of the most important factors to consider when choosing or assessing a White Drive hydraulic motor.

Maximum Operating Pressure

The maximum pressure rating indicates the highest fluid pressure the motor can safely withstand during operation. Exceeding this limit can lead to seal failure, internal damage, or catastrophic breakdown. White Drive motors are typically rated between 3,000 psi and 4,500 psi, depending on model and design.

It is crucial to match the motor’s pressure rating with the output of your hydraulic system pump and ensure all components (hoses, valves, fittings) are compatible. Using pressure relief valves and monitoring gauges helps prevent over-pressurization and extends motor life.

Displacement (cc/rev or in³/rev)

Displacement refers to the volume of hydraulic fluid required to turn the motor output shaft one full revolution. It directly affects torque output and speed characteristics. Motors with higher displacement (e.g., 100+ cc/rev) generate more torque at lower speeds, making them ideal for winches, conveyors, or heavy-duty rotating equipment.

Lower displacement motors (e.g., 10–50 cc/rev) are better suited for high-speed applications such as fans or small pumps. Selecting the correct displacement ensures optimal balance between power delivery and system efficiency.

Torque Output (Starting, Running, and Peak)

Torque is the rotational force produced by the motor, measured in lb-in or Nm. High-torque capability is essential for applications involving heavy loads, such as earthmoving equipment, augers, or industrial rollers.
