Reducing Mechanical Wear With Soft Start Motor Control

A significant amount of unplanned motor maintenance traces back to the repeated stress of hard, direct on-line starts. Every time a motor starts this way, the sudden current surge and mechanical jolt place strain on components that are never designed to absorb that kind of repeated shock indefinitely without eventual wear.

Integra from Suresense reduces this wear at its source through its soft start function. Rather than the motor lurching into motion, it accelerates smoothly and without steps, meaning the mechanical force transferred to contactors, couplings and drive train components is considerably lower with every single start cycle across the equipment's operating life.

Over time, that reduction in wear shows up as fewer unplanned breakdowns, less frequent replacement of contactors and drive components, and a generally more predictable maintenance schedule. For equipment that starts and stops often through the day, this cumulative mechanical benefit

can end up being just as valuable financially as the direct energy savings Integra also provides, since unplanned downtime and emergency repairs typically cost far more than the electricity a motor consumes.

This reduction in wear becomes more significant the more frequently a motor starts and stops, making it particularly relevant for equipment operating on an intermittent rather than continuous duty cycle.
