Redefining Motor Control
The original pioneers of soft start technology, Fairford Electronics Limited have been at the
forefront of motor control innovation since the 1970’s. Fairford have manufactured and supplied
over 1 million products into the market place and are recognised as the reference point for many
control solution providers worldwide. In 2009, the need for a new technology that bridged the
gap between drive technology and soft start was recognised and the development process
began for synergy™, a new form of motor control that met the needs of those requiring the
functionality of a drive in a fixed speed application. The key aspects of a drive (energy saving
and communications) as well as original features of a soft start including internal bypass and
lower cost, meant the base design was enhanced even further.
iERS (intelligent Energy Recovery System) is Fairford’s patented energy saving system with a
combined internal bypass to save energy on lightly loaded motors. iERS reduces the voltage
and current supplied to lightly loaded motors to only allow the motor to consume the exact
amount of energy required to maintain the speed at that load. When the motor is at full load the
internal bypass closes, this reduces the losses produced by the control element. This combined
approach enables iERS to save more energy in more applications than any other competing
technology.
iERS has been market proven over the past 10 years and has now reached its latest
development realising even greater savings. Applications such as compressors, refrigerators,
pump jacks, moulding machines and chillers can typically see savings of around 8-40% of total
energy consumption when lightly loaded.
With size and cabinet capacity an ever increasing focus, Fairford developed the world’s smallest
power to size ratio motor controller. Synergy™ utilised Fairford’s globally renowned Automatic
Setup feature to programme the unit to each individual application using only a 8 button
process. Since then it has removed buttons and uses touch screen technology bringing the user
interface to even greater management levels.
With full motor overload protection as well as full data logging, upgradeable software in the field
and extensive input/output programmability, synergy™ meets all of the key design criteria.
Enabling the Intelligent Energy Recovery System (iERS)
iERS can produce energy savings in suitable applications. However, the user should have an
understanding of the application and load characteristic before enabling the feature.
Loads which exhibit frequent changes in motor torque may cause the synergy TM unit to switch
rapidly between the iERS on state and the ‘bypassed’ state as the motor torque changes. If left
unchecked, such switching may cause premature wear of the internal bypass components and
may invalidate the warranty.
If the loaded / unloaded state changes more than 4 times per minute, iERS should not be
enabled.
Applications that are typically well suited to the iERS feature include; Artificial Lift Pump Jacks,
Injection Moulding Machines, Mixers, Saws, Rolling Mills, Grinders, Hydraulic Pumps, Crushers,
Conveyors, Compressors and Vertical Transport applications.
If the user requires further support regarding the suitability of the
application, he should seek support from Fairford Electronics Ltd or
an Authorised Distributor before enabling the iERS function
