A 20% reduction in motor speed can deliver a 50% energy saving
Variable Speed Drive products are motor control systems that provide an energy-saving solution for pumps, fans and compressors.
Electric motors driving these kinds of devices account for 64% of UK non-domestic energy consumption (Source: Department of Trade and Industry).
An exponential relationship exists between the machine speed (and output) and the energy used. Therefore, the energy and cost saving potential of VSDs is significant, given that a 20% reduction in motor speed can deliver an energy saving of 50% for a typical fan or pump.
On average, this technology can offer cost savings of more than 40% and payback periods are usually less than 2 years. VSDs have the potential to make energy savings and increase profitability in almost every sector of UK business.
