Hydraulic Motor Velocity Sensors Explained in Layman’s Conditions

September 12, 2023

Hydraulic motors are finding their way into a lot more and a lot more locations in current a long time and there is a great purpose why. They are considerably more compact and can generate a lot more torque in a a lot smaller sized device. Electric powered and gas driven motors are also noisy and produce warmth. Also, the two of these types of motors often demand some kind of transmission system to control torque.

The Problems of Substantial Force Hydraulic Technique

However hydraulic motors do have their own shortcomings that have to be dealt with. For occasion, they need a source of high strain hydraulic fluid be ran to them for the motor to work. High stress hydraulic fluid presents its possess issues in dealing with and shifting it.

A Tightly Sealed Technique

For instance, due to the truth the a hydraulic motor includes and is driven by substantial strain hydraulic fluid they need to have to be tightly sealed. This by mother nature prevents the use of a normal pace sensor that uses a cable that is related to a equipment in the motor.

The Corridor Effect

So what is the reply? The response is to use velocity sensors that use magnets to gage the speed of a hydraulic engine from the outside the house. So how can a magnet gage the speed of some thing? When an electrical existing is ran perpendicular to a magnet, the present will be effected when the magnet is in the presence of a ferrous metallic these kinds of as iron or steel. hydraulic press supplier referred to as the “Corridor effect”

Counting Equipment Teeth or Turbine Blades

So a magnetic sensor is used to count the rotations of a gear or a turbine blade that is in the hydraulic motor or the hydraulic fluid line. Each and every time a tooth of the equipment or a blade on the modest turbine passes the magnetic hydraulic motor velocity sensor, an electric powered pulse is designed that is then sent by wire to a velocity gage.
