Basic introduction to eddy current dynamometers?

　　With the continuous advancement of science and technology, various industries have also developed significantly. The development prospects of the eddy current dynamometer are quite good, so the demand is constantly increasing, and many manufacturers have emerged in the market. As a manufacturer, it is necessary for us to explain this to everyone.Eddy Current Dynamometeris a basic introduction, and interested friends can take a look together.

　　Before using this eddy current dynamometer, there are many questions that accompany everyone. Therefore, to use it better, one must understand some knowledge points about it. First, you should be clear that the eddy current dynamometer has always been widely used in the domestic market as a measurement and testing device, utilizing the principle of electromagnetic induction to form torque and power consumption. It mainly consists of an eddy current brake (rotor part, eddy current ring, excitation winding, etc.), force measuring element, speed measuring element, and control system. Now, this product consists of a dynamometer, controller, and force measuring device, which can measure the output torque and speed of the tested machine, thereby obtaining the output power. In addition, this eddy current dynamometer can replace magnetic powder clutches, hydraulic dynamometers, DC generator sets, etc., to measure the performance of various power machinery such as electric motors, gasoline engines, diesel engines, and gearboxes, becoming an essential device for type testing. Compared with other dynamometer devices, it has higher reliability, practicality, and stability.

　　The principle of the eddy current dynamometer is that when direct current passes through the excitation coil assembled coaxially with the rotor, the magnetic flux generated forms a closed loop through the eddy current ring, air gap, and rotor. Since the rotor and the swinging part are made of magnetic materials, the magnetic resistance is very small, so the magnetic flux density at this time mainly depends on the size of the air gap. The outside has a uniform tooth groove, and when the magnetic induction changes at any point of the air gap and the inner surface of the armature or eddy current ring, it will generate its magnetic field, causing the eddy current potential to be induced and obtaining eddy currents. At the same time, the eddy current dynamometer naturally undergoes eddy currents and magnetic field coupling, with the rotor generating a braking torque, while the swinging body generates a torque equal to the drag torque, which can be detected by sensors. In addition, the power output from its engine is converted into equivalent heat of the swinging body, which is carried away by the cooling water continuously entering the inner surface of the armature or the cooling water tank of the eddy current ring. This naturally ensures the long-term normal operation of the eddy current dynamometer, preventing scaling in the dynamometer's cooling chamber from affecting the cooling effect and causing damage to the dynamometer. Therefore, the purification of cooling water is quite important. There are quite a few well-reviewed manufacturers on the internet, and this company's official website has a variety of different products. Consumers have a high evaluation of it. Moreover, the company's official website also contains a lot of information about the products and tips for purchasing, etc.

　　The above article provides a basic introduction to the eddy current dynamometer for friends. Friends can read it carefully. Of course, there is still a lot of information about it. We will continue to update in the future.
