Systematic Parametric and Sensitivity Analysis of Permanent Magnet Synchronous Motor for Water Pump Application

This paper proposes the design and evaluation method to decrease torque ripple for Surface mounted Permanent Magnet Synchronous Motor (SPMSM). SPMSM type was adopted because it has the advantage of high efficiency and convenience of control for water pump. The design proceeds based on designing a motor with reduced torque ripple and magnet volume compared to motor in reference, and this paper uses Finite Element Analysis (FEA) method to evaluate different kinds of rotor. Then, proceed with a design that shows the optimal torque ripple by adjusting the offset and angle.
