Abstract
In India, some states have a depth of ground water reaching beyond 300–450 m from the ground level. Traditionally, submersible induction motor (SIM)-based pump sets are considered for irrigation. However, SIMs are no longer a good choice for deep bore wells, since there exists a reduction in its operating point, resulting in lower discharge. Based on these facts, submersible brushless permanent magnet motor (SBLPMM) is considered. The proposed SBLPMM is designed for 15 kW with an objective of high torque and power density within the given volumetric and diametric constraints. The proposed SBLPMM will reduce the number of impeller stages when compared with SIMs and hence it will be a viable alternative to the SIMs and hence paying the way for effective energy conservation. The study concentrates on the optimal selection of the geometrical poles and the finite element mesh-based results confirm that the operating efficiency is enhanced with the SBLPMM.
