Hydraulic Motor Velocity Sensors Defined in Layman’s Terms

September 12, 2023

Hydraulic motors are obtaining their way into a lot more and a lot more spots in recent many years and there is a great cause why. They are far more compact and can generate far more torque in a considerably smaller sized sized device. Electrical and gasoline powered motors are also noisy and generate heat. Also, both of these types of motors usually call for some kind of transmission method to regulate torque.

The Problems of High Force Hydraulic Program

However hydraulic motors do have their own shortcomings that have to be dealt with. For occasion, they call for a resource of higher strain hydraulic fluid be ran to them for the motor to run. Large strain hydraulic fluid provides its personal troubles in handling and moving it.

A Tightly Sealed System

For instance, thanks to the fact the a hydraulic motor includes and is powered by higher strain hydraulic fluid they want to be tightly sealed. This by character prevents the use of a normal pace sensor that employs a cable that is related to a gear in the motor.

The Hall Impact

So what is the response? hydraulic power machine is to use speed sensors that use magnets to gage the speed of a hydraulic motor from the exterior. So how can a magnet gage the velocity of one thing? When an electrical current is ran perpendicular to a magnet, the existing will be effected when the magnet is in the presence of a ferrous metal this kind of as iron or metal. Its referred to as the “Hall influence”

Counting Gear Tooth or Turbine Blades

So a magnetic sensor is employed to count the rotations of a equipment or a turbine blade that is in the hydraulic motor or the hydraulic fluid line. Every single time a tooth of the equipment or a blade on the little turbine passes the magnetic hydraulic motor pace sensor, an electric powered pulse is created that is then despatched by wire to a pace gage.
