Things You Should Know When Buying Hydraulic Motors

Hydraulic motors have found their place more and more in recent years, and for good reason. They are much more compact and can produce more torque in a much smaller size. 

Electric and gasoline engines are also noisy and generate heat. In addition, both types of engines often require some type of torque transfer system. You can also look for the best hydraulic motors via the web.

High-pressure hydraulic system problem

However, hydraulic motors have their own drawbacks that need to be addressed. For example, they need a source of high-pressure hydraulic fluid to keep the engine running. High-pressure hydraulic fluid creates its own operational and movement problems.

Tightly closed system

Since hydraulic motors contain, for example, high-pressure hydraulic fluid and are driven by it, they must be tightly sealed. This of course prevents the use of standard speed sensors that use wires connected to the gearbox in the engine.

Hall Effect

So what's the answer? The answer is the use of a speed sensor that uses a magnet to determine the speed of the hydraulic motor from the outside. How can a magnet measure the speed of something? 

Counting turbine wheels or blades

Magnetic sensors are used to calculate the rotation of gearboxes or turbine blades located in hydraulic motors or in hydraulic fluid lines. 

Each time the gear teeth or small turbine blades pass through the magnetic speed sensor of the hydraulic motor, an electric pulse is generated, which is then sent to the speedometer via a cable.
