Winding machine manufacturers: the principle of winding machine protection equipment inverter! Vacuz machinery and everyone to take a look!

Winding machine automatic protection equipment series of products on the new project of the ring winding machine inverter adjustment is to use the operation of the input inverter to simulate the working 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 changes with the original working frequency of the output. The speed ratio of the three-phase asynchronous motor is determined by the point frequency of the motor, the polarity of the motor, and the turndown rate. The rotational distance of an induction motor is produced by the interaction of the magnetic flux and the 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, which seriously damages the motor. Therefore, the change of frequency should be proportional to the working voltage, i.e. the change of frequency should be controlled with the inverter output voltage so that the magnetic flux of the motor is maintained to prevent the magnetic weakness and magnetic saturation problem. Because the general inverter generally uses V / F control, that is, DC transformer frequency conversion method speed regulation, change the frequency and operating voltage, so that the motor control measures Z good. Therefore, frequency control is used. Variable frequency speed control is to change the frequency of the motor stator switching power supply, and then change its speed ratio with the step.

It has the following characteristics.

(1) high efficiency, no additional loss in the whole process of speed regulation.

(2) Wide range of use, can be used for cage asynchronous motors.

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

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 divided into two types: the operating voltage type is the converter that converts the AC current from the voltage source to the communication, and the filter circuit of the DC circuit is the capacitor. The current flow type is a converter that converts AC power from a current source to AC power, and its DC control circuit filter is an inductor. It consists of three parts, the frequency switching power supply into the “electronic rectifier” DC output power, in the grid-connected inverter digestion absorption and inverter power caused by the current pulsation drink “plane wave control circuit”.
