Our primary technology for improving the performance of electric motors is 'Powerboss' – a range of variable torque drives from 3 hp to 1600 hp which lower motor operating temperatures and reduce energy consumption.

THE PROBLEM: AC motors are only efficient at, or close to full-load, but many motors are over-sized and typically operate well below full-load. For example, a motor operating below 50% of load can still draw 80-90% of its full-load power draw. This wasted energy takes the form of heat, noise and vibration - all of which reduce motor life and increase maintenance problems.

THE SOLUTION: Powerboss, the culmination of 10 years' R&D in the field of optimum motor efficiency, uses the latest in micro-controller technology to monitor the load requirements (torque) of a motor, and then control its power-draw to exactly match that load 120 times a second.

Powerboss improves motor performance in 4 ways:

• A Soft-Start that is fully programmable and pays for itself over time
• Energy-savings whenever the motor load falls below 65% of full-load
• Cooler motor operation - typically more than 20 degrees cooler, which extends motor life and reduces maintenance & downtime
• Timed ‘switch-off’ provides 100% savings by switching equipment off if there is no activity for a (user-adjustable) period, e.g. during lunch hours or maintenance.

The nearest comparable technology is a Variable Speed Drive (also called Variable Frequency Drives or Voltage Inverters), which are designed to change the speed of a motor to match varying loads. By contrast, Powerboss is not used in variable speed applications, but is used in constant speed applications where the load is variable.
