Introduction to the principle of electric screw machine

One. The electrical control system of the microcomputer controller electric screw air compressor is the key system of the electric screw compressor. Its main function is to reduce the voltage and reduce the starting current when the three-phase asynchronous motor (capacity is greater than 10KW) is started, so as not to generate excessive power in the power supply line. Voltage drop to reduce the impact on the grid.
