Winding machine manufacturer: the principle of the protection equipment inverter of the winding machine! Vacuz Machinery and everyone to take a look at it!

Winding machine automatic protection equipment series of products on the new project of the ring winding machine inverter adjustment is the use of input inverter operation to simulate the operating voltage, so as to control the frequency of the output switching power of the inverter, so that the communication speed ratio of the AC motor with the output of the original operating frequency and change. The speed ratio of a three-phase asynchronous motor is determined by the point frequency of the motor, the polarity of the motor, and the rate of rotation. The rotational distance of an induction motor is produced by the interaction of magnetic flux and stator current. At a fixed frequency, if the operating voltage is certain and only the frequency is reduced, the magnetic flux is too large and the magnetic control circuit is saturated, severely damaging the motor. Therefore, the change of frequency should be proportional to the operating voltage, i.e., the change of frequency should be controlled with the output voltage of the inverter, so that the magnetic flux of the motor can be maintained at a certain level to prevent magnetic weakness and magnetic saturation problems. Because the general inverter is generally used V / F control, that is, DC transformer frequency mode speed regulation, change the frequency and operating voltage, so that the motor control measures the best. Therefore, frequency control is used. Frequency regulation is to change the frequency of the motor stator switching power supply, and then change its speed ratio with the step.

It is characterized:

(1) High efficiency, no extra loss in the whole process of speed regulation;

(2) Wide range of use, can be used for cage-type asynchronous motor;

(3) speed regulation, hard characteristics, high precision. Principle of communication AC inverter: The new technology of frequency conversion is based on the inverter to change the switching frequency of the power supply, and then change the speed of the communication AC asynchronous motor. According to the inverter, the first communication to DC conversion, and then according to the inverter DC to communication conversion, and then control the communication speed ratio of AC motor. Ring winding machine automatic protection equipment series of new project products of the ring winding machine frequency regulation is to use the input inverter operation to simulate the working voltage, so as to control the frequency of the inverter output switching power supply, so that the communication speed ratio of the AC motor with the output of the original working frequency.

The main circuit is the electrical energy conversion part, which supplies the transformer radio switching power supply to the asynchronous motor. The main power supply circuit of the inverter can be roughly categorized into two types: the working voltage type is the converter that converts the AC current from the voltage source to the communication, and the filtering circuit of the DC circuit is a capacitor. The current flow type is a converter that converts AC from a current source to AC, and its DC control circuit filter is an inductor. It consists of three parts, the frequency switching power supply into “electronic rectifier” DC output power, in the grid-connected inverter absorption and inverter power supply caused by current pulsation drink “plane wave control circuit”.
