How Motor Controllers Reduce Industrial Energy Bills

Since motors can account for around half of an industrial energy bill, and considerably more in some processes, even a modest efficiency improvement on the motor side of an operation has a noticeable knock-on effect on total energy costs. Understanding how that improvement actually happens helps explain why load sensing motor control has become a practical, widely applied energy saving measure.

Integra from Suresense achieves its reduction by continuously matching motor power output to the real task at hand, rather than the fixed, worst case load a motor was originally sized to handle. It converts the motor into its own load sensor, recalculating and adjusting power roughly every 10 milliseconds so energy use tracks actual demand throughout the day rather than sitting fixed at a constant level.

The scale of the saving depends on how variable a given motor's workload is, with the most fluctuating applications typically seeing the largest reduction, often in the 10% to 40% range.

Because Integra requires no change to the underlying process or equipment, and is designed and built in the UK by Suresense, it's a comparatively low disruption way for industrial sites to bring motor-related energy costs down without a wider infrastructure overhaul.

Suresense can provide an estimate of likely savings for a specific site based on motor size, duty cycle and running hours, giving a clearer picture of the business case before any commitment is made.
