These are the benefits of soft starters

The best way to soft start is with a static frequency changer where you have full control of the electric motor's start and stop. But if you only need to have start/stop without regulating the actual speed, a soft start is a good alternative at a reasonable cost.

There are many advantages in soft starting, for example, pump and fan motors. It reduces the voltage when starting, which reduces the motor's torque, which in turn reduces the mechanical strains and wear and tear on bearings and driving belts.

For equipment with many starts a day there is a certain reduction in energy use at the same time that smaller fuse sizes can save money in the form of lower fixed costs. In many installations a soft starter is a must. For example, an escalator that has a jerky start is not desirable.

Soft started equipment lasts longer than direct or Y/D-started motors and provides lower service and maintenance costs. The absence of high start current during a soft start also reduced the strain on the electrical network. A direct-started motor results in a high start current that can disrupt other motor operations and other electrical equipment.

Possible to save energy and a question of comfort

For equipment with several starts every day there is a certain reduction in energy consumption, while at the same time a lower fuse rating can generate savings in the form of lower fixed charges. A soft start is a must in many installations. You don't want an escalator that shudders into action.
