Due to the demand for more powerful photovoltaic irrigation systems, a 3.8 kW permanent magnet synchronous motor (PMSM) has been designed and developed. The higher efficiency of PMSMs compared to induction motors is shown. A standard induction motor having a squirrel cage rotor and a permanent magnet rotor are studied for comparison purposes. In order to avoid the use of a position sensor, an additional rotor cage for "open loop" operation is implemented.
