What can VSDs offer for fixed torque applications?

ABB’s Andrew Bould explains why fixed torque applications shouldn’t be overlooked as candidates for variable speed drive installation. When we talk about variable speed drives (VSDs), the focus is very often on energy saving. Indeed, in variable torque applications like fans and pumps they can reduce energy costs by up to 60 percent. However, when it comes to fixed torque applications such as conveyors, compressors, mixers and hoists, energy savings are still achievable but are…
