Hydraulic motors are actuators that mechanically converts the flow of hydraulic pressure into torque and angular rotation through a medium( hydraulic hoses ).Hydraulic motor performs the opposite of the works done by hydraulic pumps.Hydraulic motor is the interchangeable and the rotary mechanised as a hydraulic cylinder.

One of the major different between a hydraulic motor and pumps is that the pump cannot be back driven.

Electric motors , pumps and hydraulic cylinder can be formed together to manufacture a particular hydraulic transmission.

Types of hydraulic motor:

a) Radial piston motors:

it consists of the crankshaft type and multilobe cam ring types. The crankshaft type has a piston and cam pushing inwards while the multilobe type has a cam ring with more lobe and piston rollers pushing outwardly.

b). Gear and vane motors:

it has two gears, the driven gears and the idler gears.

C). Gerotor motors:

is a rotor device with n-1 teeth. These Gerotor are of low - medium speed and medium- high torque.

d). Axial plunger motors:

is used with a gear box. They have a very high rotating capacity.
