11.1Nm 100000 Rpm High Precision High Speed Dynamometer
Overview
The eddy current dynamometer uses the principle of eddy current loss to absorb power.
The dynamometer is composed of dynamometer, controller and force measuring device, which can measure the output torque and speed of the machine to be measured, so as to obtain the output power.
The eddy current dynamometer can replace the magnetic powder clutch, hydraulic dynamometer, DC generator set, etc., which is used to measure the performance of various electric motors, gasoline engines, diesel engines, gear boxes and other power machinery, and becomes the necessary equipment for type test
operating principle
According to the structure of eddy current dynamometer, the inductor is mainly composed of rotating part and swinging part (armature and excitation coil). The shape of the inductor on the rotor shaft is like a gear, and there is a DC excitation coil coaxial with the rotor.
When a DC current is passed through the field coil group, there is a magnetic field around it, and a closed flux is generated around the field group.It is evident that the inductor on the left side of the winding has one polarity and the right side has the opposite polarity.
When high speed rotation dynamometer, due to the cycles of the flux density values produce eddy current, the eddy current magnetic field with its magnetic field interaction, and commissioning are produced by reverse braking torque, the armature oscillating, through the lever on the armature, the braking force to the measuring device, by the size of the force sensor will force into electrical signal output, so as to achieve the purpose of measuring the torque.
