1. requires less power to start up
The motor power is proportional to the product of the current and voltage, so the power consumed by the motor directly driven by the power frequency will be much higher than the power required for the inverter start. In some working conditions, its power distribution system has reached the highest limit, and the surge generated by its direct power frequency starter motor will have a serious impact on other users on the same network. If the inverter is used to start and stop the motor, no similar problem will occur.
2. controllable acceleration function
The screw machine frequency control can start at zero speed and accelerate evenly according to the user's needs, and its acceleration curve can also be selected (linear acceleration, S-shaped acceleration or automatic acceleration). When the power frequency is started, the motor or the connected mechanical part shaft or gear will generate severe vibration. This vibration will further exacerbate mechanical wear and tear and reduce the life of mechanical components and motors. In addition, variable frequency start-up can also be applied to similar filling lines to prevent the bottle from falling over or being damaged.
