Fully automatic coil winding machine can generally understand the quality of the products produced by the coil winding machine through overspeed experiments, but how to measure is the correct method?
The correct overspeed experiment operation method of the automatic coil winding machine is very simple, which is to increase the speed of the automatic coil winding machine to more than 120% of the rated speed. Test the mechanical strength of each part of the rotor to withstand the centrifugal force and the mechanical strength of the bearing at overspeed, and test the quality of the automatic coil winding machine under high strength and full load.
The over-speed operation of the automatic coil winding machine has another advantage, which is that it can increase the frequency of the power supply voltage of the tested winding machine, or use an auxiliary winding machine to drag the tested winding machine to increase its speed. In addition, the method of improving the power supply and voltage frequency of the fully automatic winding machine currently all use the SCR variable frequency device-variable frequency power supply. The way to increase the speed is very simple, reduce the excitation current or increase the armature end voltage. But the increase in terminal voltage is less than 130% of the rated voltage, and reducing the excitation current will make the speed rise steadily.
In this case, it is a very strict test for the fully automatic coil winding machine machine. If it can support 2min at an increased speed without deformation or other abnormal conditions, such a fully automatic coil winding machine is qualified. When buying a fully automatic coil winding machine, you usually consider the price, whether it is suitable for your needs, etc., but there are not many ways to test the equipment, so you can let the manufacturer do this experiment.
