Mechanical equipment

 The power device of mechanical equipment mainly comes from the AC motor, and the motor at start, the current will be 5-6 times higher than the rated, not only will affect the service life of the motor and consume more electricity. In the design of the system, there will be a certain margin in the selection of the motor. The speed of the motor is fixed, but in the actual use process, sometimes to run at a lower or higher speed. In this case, SAJ inverter is usually installed to realize soft start of the motor, achieve the purpose of energy saving speed regulation by changing the input voltage frequency of the equipment, and provide the equipment with over current, over voltage, overload and other protection functions.
