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.
