The future of soft start motor control at your fingertips





As the original pioneers of soft start technology Fairford have been at the forefront of motor control innovation since the 1970’s.

A major designer and manufacturer of soft start motor control solutions Fairford have manufactured and supplied 1,000,000’s of products into the market place and are recognised as the reference point for many control solution providers worldwide. Synergy™ is an innovative form of motor control that bridges the gap between

a drive and a soft starter. With the increasing pressure on industry to lower its energy consumption and increase systems efficiency, synergy™ has been developed to meet these requirements.
in addition, synergy™ utilises Fairford’s globally renowned automatic setup feature which allows the user to programme the unit to each

individual application using a simple 8 button process. Not only that but in order to keep pace with modern technology and a fast growing market, buttons are replaced with a touch screen to bring the user interface to even greater management levels.
With built in full motor overload protection as well as full data logging, field

serviceable, upgradeable software, extensive input/output programmability synergy™ meets all of the industrial fixed speed criteria.
More importantly it redefines motor control solutions as we have previously known them.


iERS – intelligent Energy Recovery System

iERS is an advanced motor control technology for use in fixed speed applications. It is proven to reduce the energy consumed in a variety of industrial and commercial applications and has been implemented in every market from HVAC to Oil and Gas.
In the industrial sector it is becoming increasingly important to offer technology that meets the corporate social responsibilities of companies as well as reducing the overall running costs of equipment and minimising downtime and maintenance.
iERS is a technology that matches the power consumption to the load required. It intelligently monitors and regulates energy consumption on fixed speed motors. It also monitors the voltage, current and power factor during the start to calculate the full load figures. During the running stage, the power factor continues to be monitored.

When the power factor drops, the motor is lightly loaded,and there are losses inherent in the design of a motor causing excess energy to be wasted. These are known as excitation losses. iERS’s consistent monitoring automatically recognises these costly losses, and in turn reduces the voltage and current, to not only increase the part load power factor, but reduce the energy consumption in kW. When the power factor increases, the motor is more loaded. iERS then automatically bypasses itself to remove any losses within the equipment.
