What does the dynamometer manufacturer say about it?

　　The emergence and development of any industry are inseparable from the progress of science and technology, which is also driven by the expanding market demand, prompting relevant personnel to continuously update and upgrade products. In the processing industry, these requirements are even more numerous. For example, the processing of dynamometers has also transitioned from traditional craftsmanship to more advanced technological processing. So what are its characteristics? At the same time, when using it, we...Dynamometer manufacturersWhat should be noted?

　　Dynamometer manufacturers say that a dynamometer, also known as a power meter, is mainly used to test the performance of engines and can also serve as a loading device for gearboxes, reducers, and gearboxes to test their transmission performance. It is mainly divided into hydraulic dynamometers, eddy current dynamometers, and electric dynamometers. Electric dynamometers measure the torque output of various mechanical power shafts using engines and determine power in conjunction with speed. Since the tested power machinery can have different speeds, the motor used as an electric dynamometer can be a continuously variable speed motor. Common types include DC dynamometers, AC dynamometers, and eddy current dynamometers. According to the structural diagram of the eddy current test bench, the inductor mainly consists of a rotating part and a vibrating part (armature and excitation coil). Dynamometer manufacturers say that the inductor on the rotor shaft is shaped like a gear, and the DC excitation coil is coaxially mounted with the rotor. When the excitation coil group passes direct current, a magnetic field is generated around it, producing closed magnetic flux around the excitation group. It is evident that the inductor on the left side of the winding has one polarity, while the right side has the opposite polarity.

　　Dynamometer manufacturers say that during rotation, due to the periodic change in magnetic density, eddy currents are generated, and the magnetic field interacts with the magnetic field that produced it, generating a counteracting torque against the tested machine, causing the armature to oscillate, where the torque arm transmits the braking force to the measuring device through the armature. Speed measurement uses a non-contact magnetic electric speed sensor and a 60-tooth gear disc mounted on the spindle, converting the speed signal into an electrical signal output. The working principle of the hysteresis dynamometer is mainly that the hysteresis dynamometer consists of a toothed pole stator, a hollow hysteresis cup rotor, an excitation coil, a bracket, a base plate, and other components. When current passes through the internal coil of the hysteresis dynamometer, magnetic force lines are generated, forming a magnetic circuit that produces torque. By changing the excitation current, the load torque can be altered.

　　Dynamometer manufacturersIt is said that dynamometers are mainly suitable for testing medium and small torque and high-speed motors, such as constant torque load starting motors, asynchronous motors, small power DC motors, inline motors, and various electric tools, etc.
