What is the overspeed detection method of automatic winding machine?

Automatic winding machine generally do overspeed experiment can know the winding machine to make product quality is how, but how to measure is the right way? Take you to understand the next automatic winding machine correct overspeed experimental operation method!

The correct overspeed test operation method of automatic winding machine is very simple, that is, to increase the speed of our automatic winding machine to 120% of the rated speed. Test the mechanical strength of each part of the rotor under centrifugal force and the mechanical strength of the bearing in overspeed, check the quality of the automatic winding machine under the condition of high strength and full load.

The overspeed operation of the automatic winding machine has another advantage, which can improve the frequency of the source voltage of the tested winding machine, or drag the tested winding machine with the auxiliary winding machine to improve its speed. In addition, the method of improving the power supply and voltage frequency of the automatic winding machine is currently adopted the SCR frequency conversion device - frequency conversion power supply. The way to increase the speed is simple, reduce the excitation current or increase the voltage at the armature. However, the increase of terminal voltage is less than 130% of the rated voltage, and reducing the excitation current will make the speed rise steadily.

In this case for fully automatic winding machine is a kind of very strict test, if it is in high speed can support the below 2 min, no deformation or other abnormal condition, the automatic winding machine in order to be eligible, everybody to buy fully automatic winding machine, usually will consider price, whether it's appropriate own demand, etc., but isn't much of a clue on how to test equipment, Let the manufacturer do the experiment.
