Abstract

A typical diagram-configuration photovoltaic (PV) water pumping system consists of a d.c. permanent magnet motor driving a diaphragm pump via a cam. The typical efficiency is low and the lifespan short. The use of a linear d.c. motor or actuator as the drive is suggested. A higher efficiency and life expectancy could be achieved. The aims of this project were to measure the pump, evaluate possible electromagnetic configurations with a finite-element analysis (FEA) package and to evaluate different electromechanical options. The results obtained for these criteria will be discussed concluding with a choice of the best topology.
