The correct operation method of over speed experiment for automatic bldc motor stator coil winding machine

Automatic winding machine debugging video_Automatic winding machine common faults_Automatic winding machine correct over-speed experimental operation method: Automatic winding machine generally do over-speed experiment is to know the quality of the product made by the winding machine is how, but how to measure the correct method? Take a look at the correct speed test operation of automatic winding machine!

Automatic winding machine correct overspeed test operation method is very simple, is to increase the speed of our automatic winding machine to more than 120% of the rated speed. Test the mechanical strength of the rotor parts to withstand the centrifugal force and the mechanical strength of the bearings at over speed, and test the quality of the automatic winding machine under high strength and full load.

The over-speed operation of the automatic winding machine has another benefit, it can increase the frequency of the supply voltage of the tested winding machine or drag the tested winding machine with an auxiliary winding machine to increase its speed. In addition, the method of increasing the power supply of the automatic winding machine, voltage frequency, are currently using silicon controlled variable frequency devices – variable frequency power supply. And the method to increase the speed is simple, reduce the excitation current or increase the armature end voltage. However, the increase in end voltage is less than 130% of the rated voltage, and reducing the excitation current will result in a smooth increase in speed.

In this case for the automatic winding machine is a very strict test, if it can support 2min at increased speed, no deformation or other abnormal conditions, so that the automatic winding machine is considered qualified, people in the purchase of automatic winding machine, usually consider the price, whether it is suitable for their needs, etc.
