Hydraulic Motor Pace Sensors Explained in Layman’s Phrases

Hydraulic motors are discovering their way into more and much more places in latest a long time and there is a good cause why. They are far a lot more compact and can produce a lot more torque in a significantly smaller sized unit. Electric powered and fuel driven motors are also noisy and make heat. Also, both of these varieties of motors often need some variety of transmission method to regulate torque.

The Problems of Large Strain Hydraulic Technique

Even so hydraulic motors do have their possess shortcomings that have to be dealt with. For occasion, they require a supply of higher force hydraulic fluid be ran to them for the motor to operate. Higher strain hydraulic fluid provides its personal difficulties in dealing with and moving it.

hydraulic power machine Sealed Technique

For instance, owing to the fact the a hydraulic motor is made up of and is powered by higher stress hydraulic fluid they need to have to be tightly sealed. This by nature helps prevent the use of a common speed sensor that utilizes a cable that is related to a gear in the motor.

The Hall Influence

So what is the reply? The answer is to use velocity sensors that use magnets to gage the pace of a hydraulic motor from the outside. So how can a magnet gage the pace of something? When an electrical recent is ran perpendicular to a magnet, the existing will be effected when the magnet is in the existence of a ferrous metallic these kinds of as iron or metal. Its called the “Hall impact”

Counting Gear Tooth or Turbine Blades

So a magnetic sensor is utilised to rely the rotations of a equipment 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 little turbine passes the magnetic hydraulic motor speed sensor, an electric pulse is developed that is then sent by wire to a pace gage.
