What is the correct operation method of overspeed experiment for automatic winding machine?

The automatic winding machine generally does the overspeed test to know the quality of the product made by the winding machine, but how to measure it is the correct method? Take you to understand the correct operation method of overspeed experiment of automatic winding machine!

The correct operation method of the overspeed experiment of the automatic winding machine is very simple, that is to increase the speed of our automatic winding machine to more than 120% of the rated speed. Test the mechanical strength of each part of the rotor bearing centrifugal force and the mechanical strength of the bearing in the case of overspeed, and test 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 increase the frequency of the power supply voltage of the tested winding machine, or use the auxiliary winding machine to drag the tested winding machine to increase its rotational speed. In addition, the method of improving the power supply and voltage frequency of the automatic winding machine adopts SCR frequency conversion device-frequency conversion power supply at present. The method to increase the speed is very simple, reduce the excitation current or increase the armature terminal voltage. However, the increase of the terminal voltage is less than 130% of the rated voltage, and reducing the excitation current will make the speed rise steadily.

In this case, the full-automatic winding machine is a very strict test, if it can support 2min at increased speed, no deformation or other abnormal conditions, such a full-automatic winding machine is qualified, when you buy a fully automatic winding machine, you will generally consider the price, whether it is suitable for your needs, etc., but there are not many clues on how to test the equipment, you might as well let manufacturers do this experiment.
