Synchronous reluctance motors (SynRMs) are an alternative solution in low‐cost applications due to some advantages in terms of manufacturing simplicity. This study deals with a new design and implementation of a SynRM so as to operate at low‐voltage level produced by solar panels without using any boost‐converter. A 4‐inch of standard frame size is chosen for as a submersible pump motor. Preparing for the optimisation step, the commercial design software, Infolytica is used to create the first base structure of the SynRM. As the first step the dc‐link voltage, rated current, rated speed, winding layout, slots number, number of the rotor barriers and the outer/inner diameters of the stator are determined. In the next step, the base structure is optimised by using a genetic algorithm (GA) developed in Matlab environment. The developed GA script and finite element analysis software are operated together for optimisation of the rotor geometry. A direct torque control algorithm is used to analyse the performance of the designed motor. The designed motor is also manufactured and tested experimentally.
