Application of frequency converter

When the CNC lathe is started, the current of the motor will be 5-6 times higher than the rated value, which will not only affect the service life of the motor but also consume more power. The system will have a certain margin in the selection of the motor during the design. The speed of the motor is fixed, but in actual use, sometimes it runs at a lower or higher speed, so it is very necessary to carry out frequency conversion transformation. The inverter can realize the soft start of the motor, achieve the purpose of energy saving and speed regulation by changing the input voltage and frequency of the equipment, and can provide the equipment with protection functions such as overcurrent, overvoltage and overload.
