What are the advantages of an eddy current dynamometer?

　　With the continuous advancement of science and technology, various industries have also made significant progress. The development prospects of the eddy current dynamometer are also 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 the advantages of the eddy current dynamometer here. 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 a simple structure, stable operation, low cost, and convenient maintenance, and can conduct type tests on various motors and power machinery. Moreover, this product's controller uses single-phase AC power supply, with low control power; especially, the torque measurement of this product can use electronic scales, pressure sensors, or high-precision torque and speed measuring instruments, suitable for different measurement accuracy occasions. This device can also be used as a brake, with relatively high braking torque. The ambient temperature should not exceed 40°C, and the altitude should not exceed 1000m. At an ambient temperature of 30°C, the relative humidity should not exceed 85%. The input speed regulation range is wide, suitable for various frequency conversion speed regulation motors and dynamic mechanical testing instruments. The eddy current dynamometer uses a single-phase AC power supply with low control power.

　　The difference between the eddy current dynamometer and the hysteresis dynamometer: the magnetic powder dynamometer consists of magnetic powder, rotor, armature, excitation winding, torque sensor, speed sensor, base plate, etc. Now, this eddy current dynamometer has coils on the stator, and the relevant parts of the stator and rotor form a magnetic circuit. A certain amount of magnetic powder is added to the working gap between the stator and rotor. When the coil is energized, the product generates magnetic flux in the magnetic circuit, and the magnetic powder forms a magnetic powder chain under the action of electromagnetic force. When the rotor rotates, the stator acts on the rotor through the magnetic powder chain, generating braking torque. By changing the current in the coil, the size of the electromagnetic attraction can be adjusted, thereby controlling the braking torque. At this time, the product mainly consists of a stator with toothed magnetic poles, a hollow hysteresis cup rotor, excitation coil, base plate, etc. When the internal coil of the hysteresis dynamometer is energized, magnetic field lines are generated, forming a magnetic circuit to produce torque. In this case, the hysteresis torque of the dynamometer is changed by altering the excitation current, thus achieving the purpose of controlling the load torque and completing the load characteristic test. The eddy current dynamometer, also known as a dynamometer, is mainly used to detect the input voltage, current, power factor, frequency, input electrical power, and output torque of motors. The company is committed to expanding and developing domestic and international markets, using both online internet e-commerce platforms and offline physical sales.

　　After the introduction of the above content, we have already understood the advantages of the eddy current dynamometer. Other knowledge points will continue to be updated in the next issue, so if you have time, remember to come and watch.
