A hydraulic motor is the actuator that turns hydraulic pressure into torque and rotation. There a few types of hydraulic motors, all geared to a specific purpose.

Gear and vane hydraulic motors

This is the more simple of the range of hydraulic motors and is commonly implemented. The benefits of this motor include the low cost of manufacture and the high rate of revolutions delivered. The force of the hydraulic fluid which enters the cylinder on one end and exits on the other causes the the rotor to spin in one direction. Another benefit of the gear and vane motor is that breakdowns occur less frequently than in other motors.

Gerotor motors

A rotor with one less teeth to the gear than the rotor in which it is rotating at the centre. Hydraulic fluid is guided under pressure into the assembly to actuate motion. There are a number of varying designs on this concept.

Axial plunger motors

The most commonly used of all the hydraulic motors, the Axial plunger motor is preferred because the machinery being driven by a motor is often lower than the motor produces and this can be controlled through the addition of gears.

Radial piston motors

Based on a rather old fashioned design of up and down piston action the versatility of this design makes it a popular motor. One of the characteristics of the radial piston motor is the vast array of speeds at which the motor can operate equally well.

There are a number of improvements and embellishments which have become common-place as radial piston motors all of which operate well on low speeds and are capable of delivering high powered performance.
