Hydraulic motors are a fundamental part of modern machinery, playing an essential role in many applications across different industries. They are rotary actuators that convert hydraulic, or fluid energy into mechanical power. Working in tandem with a hydraulic pump, which converts mechanical power into fluid, or hydraulic power, these motors provide the force and offer the motion required to move an external load.
Common Types of Hydraulic Motors
There are three commonly used types of hydraulic motors today – gear, vane, and piston motors. Each type comes in a variety of styles and has distinct characteristics. Other less commonly used types include gerotor or gerolor (orbital or roller star) motors.
Gear motors are the most cost-effective and work best at moderate pressures and flows. They feature two gears: one is the driven gear which is mounted on the output shaft, and the other is the idler gear. High-pressure oil is ported into one side of the gears, and it flows around the gears and housing to the outlet slot and is compressed out from the motor.
Vane motors offer medium pressure ratings and high flows, with a mid-range cost. They comprise a housing with an eccentric bore, and a rotor where the vanes slide in and out.
Piston motors are the most expensive, but they offer the highest flow, pressure, and efficiency ratings. They come in a variety of designs, including radial, axial, and other less common styles.
Choosing the Right Hydraulic Motor
When selecting a hydraulic motor, several factors must be taken into consideration. These include the maximum operating pressure, speed, and torque the motor must accommodate, its displacement and flow requirements, the type of fluid it uses, and its resistance to contamination. Cost, efficiency, size, and weight are also important factors to consider.
