Hydraulic Vane Motors – Smooth, Quiet, Reliable Power

Hydraulic vane motors are compact, efficient rotary actuators designed for low-speed, high-torque applications. Known for their quiet operation, low flow pulsation, and simple serviceability, they’re ideal for both industrial and mobile machinery – from injection moulding systems to agricultural equipment.

How Vane Motors Work

A vane motor consists of a rotor mounted inside a housing with an eccentric bore. The rotor contains sliding vanes that extend outward, maintaining contact with the housing wall. As pressurised hydraulic fluid enters the motor, it creates a force imbalance across the vanes, causing the rotor to spin.

To ensure proper sealing and minimise wear, vane tips are precision-machined where they contact the housing. Various “lip” designs are used to reduce metal-to-metal contact while maintaining a tight seal. The vanes are typically pressed outward using spiral springs, leaf springs, or rods, depending on the motor design.
