ABB PSTB soft start



ABB PSTB soft start

Soft starter

When the first electric motor appeared, engineers had been searching for a way to avoid it

Electrical and mechanical issues that occur during the start-up of an electric motor. Since the early 1980s,

ABB has been producing soft starters and has valuable experience. Nowadays, these classics

Testing is also integrated into the design of product lines. The latest PST series launched by ABB is

A significant advancement in soft start technology. Applied intelligence from modern power electronics

The soft starter developed by ABB can use electronic components excellently in both circuits and software

To control the current and voltage during the starting and stopping of the electric motor, several additional components have been added

Design features.

Solutions to mechanical and electrical issues

AC electric motor - known as the "industrial pack horse", used to drive fans, crushes

Equipment such as machines, mixers, water pumps, conveyor belts, etc. In production factories around the world,

It often causes unnecessary torque and current peaks, while also causing various losses

Bad, including: electrical issues

The sudden changes in voltage and current generated during direct starting or star delta starting have caused significant impacts

Electrical issues related to quantity. These sudden changes may cause overload of the local power grid and result in

Unacceptable voltage fluctuations that affect other devices connected to the power grid.

Electric motor voltage

Direct start star/triangle start soft start

Adjustable starting point

Mechanical problems with dynamic slope curves

The entire transmission chain (from the electric motor to the driven equipment) will be subjected to severe stress,

Causing a large amount of maintenance work and even parking accidents. Operational issues

Such as pressure in pipelines, damage to products on conveyor belts, and discomfort for personnel riding elevators.

Water hammer effect and pipeline pressure fluctuation issues

Water hammer effect and pipeline pressure fluctuations often occur during the process of starting and stopping water pumps.

Behind every technical issue and malfunction, attention should be paid to the economic losses caused by maintenance and production stoppage.

A simple way to solve these problems is to install ABB's PST (B) soft starter. Got it

ABB soft starter can smoothly start and stop the motor, maximizing its performance

Reduce mechanical and electrical impacts.
