During the inspection of our automatic winding machine, there is a process to perform an over-speed experiment on the automatic winding machine. The method of this experiment is to increase the speed of our automatic winding machine to more than 120% of the rated speed. We do this to check the installation quality of the winding machine, to test the mechanical strength of the rotor parts to withstand the centrifugal force and the mechanical strength of the bearings at over speed.

Automatic winding machine over-speed operation, but also to increase the frequency of the supply voltage of the tested winding machine, or use the auxiliary winding machine to drag the tested winding machine to increase its speed. In addition, to increase the power supply of the automatic winding machine, the voltage frequency method, at present are used silicon controlled frequency conversion device – frequency power supply. And the method to increase the speed is to 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. Requirements for all automatic winding machine – it can support 2min at an increased speed without deformation, so that the automatic winding machine is considered qualified, you buy automatic winding machine, you may wish to ask the manufacturer about this experiment to see if the manufacturer also did, in doing the overspeed test, it is recommended that the speed measurement * better The use of long-range tachometer.

Common Mode Choke Coil Winding Machine

Automatic winding machine is divided into two parts: winding and line, so the transmission part of the automatic winding machine is also independent of the two parts.

The transmission of the winding part is to transfer the rotation of the motor to the chuck, so that the chuck rotates according to the established speed of the computerized automatic winding machine research and development to complete the winding action. The drive of the winding part is to convert the rotation of the stepping motor into a flat motion, and to arrange the wire according to the technical requirements. The load and precision of the two parts are different. The winding part requires high speed and high load, but not high precision, while the lineup part has low speed and light load, but high precision. Therefore, in the whole structure design, the good or bad design of the transmission system is related to the accuracy, efficiency and reliability of the whole system.

Flat belt drive relies on the inner surface of the belt ring and the outer surface of the pulley to produce friction. Commonly used flat belts are canvas core flat belts, leather flat belts, woven flat belts and composite flat belts. Generally connected with a joint into a ring, so the transmission is not smooth. The two axes are staggered, the staggering angle is usually ninety degrees, used to transfer the rotation between the two staggered axes in space, with a semi-staggered state, only suitable for one-way transmission.
