A brief introduction to eddy current dynamometers?

　　Eddy Current DynamometerThe development prospects of this industry are very good, as it brings many benefits to enterprises during use, making it very popular among customers. To help everyone become more familiar with it, we will now discuss some basic information about the Eddy Current Dynamometer. We hope it can be helpful to more people.

　　Nowadays, many people are still unaware of some basic information about the Eddy Current Dynamometer. Therefore, as a manufacturer, it is necessary for us to briefly explain it. This Eddy Current Dynamometer is widely used in the domestic market as a measurement and testing device. It utilizes the principle of electromagnetic induction to generate torque and power consumption. It mainly consists of an eddy current brake (rotor part, eddy current ring, and excitation winding), force measurement assembly, speed measurement assembly, and control system. In fact, when using it, it mainly absorbs power through the principle of eddy current loss. The dynamometer consists of a dynamometer, controller, and force measuring device, which can measure the output torque and speed of the tested machine, thus obtaining the output power. With it, the Eddy Current Dynamometer can also replace magnetic powder clutches, hydraulic dynamometers, DC generator sets, etc., to measure the performance of various power machinery such as motors, gasoline engines, diesel engines, and gearboxes, becoming essential equipment for type testing. Therefore, compared to other dynamometers, the GW/CW series dynamometers naturally have higher reliability, practicality, and stability. During operation, the direct current generates magnetic flux through the excitation coil, which is coaxially assembled with the rotor, forming a closed loop through the eddy current ring, air gap, and rotor. Since the rotor and swinging part are made of magnetic materials and the magnetic resistance is very small, the magnetic flux density mainly depends on the size of the air gap.

　　The principle of the Eddy Current Dynamometer is that its exterior has uniform teeth and grooves, creating a magnetic field in the air gap and the inner surface of the armature or eddy current ring. Any change in magnetic induction at any point induces an eddy current potential, resulting in eddy currents. At the same time, the eddy currents and magnetic field can generate a braking torque on the rotor, producing a torque equal to the dragging torque on the swinging body, which is detected by sensors. So what you see is that the power output from the engine is actually converted by the Eddy Current Dynamometer into an equivalent amount of heat flowing on the swinging body, which is continuously carried away by cooling water into the cooling slots of the armature surface or eddy current ring. To ensure that the Eddy Current Dynamometer can operate normally for a long time and to prevent scaling in the cooling chamber from affecting the cooling effect and causing damage to the dynamometer, the purification of the cooling water treatment is very important. Our products can certainly meet these needs, and we welcome friends from all over the country to establish long-term cooperative relationships. After all, we are well-known in this industry, and our prices are reasonable with guaranteed quality. You will definitely not be disappointed.
