Soft Start Motor Controllers UK

Starting a motor direct on-line is simple, but it's rough on everything connected to it. In that first moment, the motor can draw six to nine times its normal full load current, which puts real strain on the electrical supply and sends a sudden mechanical jolt through the drive train. Integra, designed and manufactured in the UK by Suresense, provides a soft start alternative that avoids all of that.

Instead of a hard, instant start, Integra ramps the motor up smoothly and without steps, bringing it up to full working speed in a controlled way. This soft starting behaviour reduces the current spike that would otherwise hit the supply, which matters both for the stability of other equipment on the same circuit and for avoiding the peak demand penalties that utility companies can apply when a large spike is detected.

There's a mechanical benefit too. A hard start can transfer significantly more shock load into gearboxes, couplings and other drive train components compared with a soft start, and that repeated stress is a common cause of premature mechanical failure.

Because Integra is built and supported in the UK by Suresense's own engineering team, businesses get both the soft start functionality and the reassurance of local design, manufacture and technical backup.
