An Improved Approach for Connecting VSDs and Electric Motors When electric motors are connected with Variable Speed Drives, some precautions must be taken. Motor cable length can create short time over-voltage at the motor terminal. This phenomenon results in premature ageing of the motor winding insulation, and, if not properly designed, will lead to […]
AC inverter drives for pump and fan applications to 630kW According to information published by Schneider Electric UK, 72 % of consumed electricity is used to turn on motors, and of this energy usage, 63 % is used for fluid applications like pumps and fans. This means that significant energy savings are available […]
How to avoid inverter variable speed drive (VSD) equipment failure Connecting motors to variable speed drives (VSDs) via cables delivers flexible control, energy efficiency, and low-cost maintenance. According to Schneider Electric UK however, four precautions are advisable to prevent overvoltage compromising motor lifetime or causing a shutdown. How cable length can […]
Effective in the UK from 2015, the Energy Savings Opportunity Scheme (ESOS) is a mandatory energy assessment and energy saving identification scheme for large undertakings for organisations employing over 250 people. They will be required to audit their total energy consumption including for buildings, industrial activities and transport and to identify cost-effective […]
Of particular interest to machine builders, Schneider Electric UK offers the Altivar 12 variable speed inverter drives in two versions depending on whether a heat sink is required. Both are rated IP20. The base-plate mounting version is designed to be fixed to the machine frame, which provides sufficient surface area to allow […]
