Protecting Drive Train Components With Motor Control

A direct on-line motor start doesn't just stress the electrical supply, it hits the mechanical transmission system hard as well. The sudden torque involved in a standard start can transfer up to 300% more shock load into gearboxes, couplings and connected drive train components compared with a controlled start, and that kind of repeated shock is a well known driver of premature mechanical failure.

Integra from Suresense removes that shock loading through its soft, step-less acceleration profile. Rather than the motor jolting into motion, it ramps up smoothly, meaning the torque delivered to the drive train builds gradually rather than arriving as a sudden spike. This is particularly relevant for heavier machinery, where the mechanical consequences of repeated hard starts tend to be more costly to put right.

The practical outcome is fewer premature failures across gearboxes, couplings and related drive train components, along with reduced repair and replacement costs over the working life of the equipment.

For sites running motors that start and stop frequently through a shift, this mechanical protection can end up being just as valuable as the direct energy savings Integra also delivers, since unplanned mechanical downtime tends to be far more expensive than the energy it saves.
