We all know that the current of the air cooler is several times of the budget quota when it is in operation. In this way, several runs will undoubtedly not only waste the excess electricity during its service period, so many air cooler manufacturers have optimized the air cooler. Let us understand next.

In equipment design, the selection of motors will have a certain capacity. Motor speed is fixed, but in specific use, it is sometimes necessary to operate at a relatively low or relatively high speed. Therefore, it is necessary to carry out frequency transformation. Variable frequency governor can change the input voltage frequency of the machine to achieve the soft start of the motor, environmental protection, energy saving and speed change, and the machine equipment to give over current, over voltage, load protection.
