When the conveyor belt machine is started, the current of the motor will be 5-6 times higher than the rated rate, which will not only affect the service life of the motor but also consume more electricity. The speed of the motor is fixed, but in the actual use process, sometimes it is necessary to run at a lower or higher speed, so it is very necessary to carry out frequency conversion transformation. SAJ inverter is a kind of equipment that can realize the soft start of the motor, achieve energy-saving speed regulation by changing the working frequency of the conveyor belt machine, and can provide protection functions such as over-current, over-voltage, and overload to the equipment.
