Description

The solution to both mechanical and electrical problems
AC motors, “the workhorse of the industry”, that are used to
drive fans, crushers, agitators, pumps, conveyors etc., are
unnecessarily causing unwanted load peaks day in and day
out in production plants all over the world. These violent starts
cause damage in several ways. Among them are:
● Electrical problems due to voltage and current transients
arising from Direct-on-Line or Star-Delta starts. Such transients may overload the local supply network and cause
unacceptable voltage variations that interfere with other
electrical equipment connected to the network.
● Mechanical problems that address the entire drive chain,
from motor to driven equipment, to severe stress.
● Operational problems, such as pressure surges in pipelines,
damage to products on conveyor belts and uncomfortable
escalator rides.
The financial consequences are considerable: every technical problem and every breakdown, costs money – in terms of
repairs as well as lost production.
The easy solution to all of these problems is to install an ABB
Softstarter type PSR, PSS or PST. With ABB Softstarters, it is
possible to start and stop smoothly while keeping mechanical
and electrical stresses to a minimum.
