Researchers from India have developed a novel PV-powered open-ended winding induction machine (OWIM) for agriculture water pumping. In an OWIM system, the endpoints for each phase are separated, ...

Developed by Egyptian scientists, the PV-powered water pumping system may produce up to 181.8 m3 of water per day. The system consists of two PV arrays with each a capacity of 4.6 kW and a pumping ...

Variable frequency drives (VFDs), also known as variable speed drives (VSDs), are used to modulate the speed of motors in various applications, from hydronic water pumping to VAV fan units to vacuum ...

Ideally suited for new commercial HVACR applications and deep retrofits, the line of fully integrated, intelligent pumping systems now features the MLE variable-speed motor in ranges of 3-30 hp for ...
