Abstract
For a given overload capability and flux-weakening speed range an effective procedure to design low-voltage synchronous motors is described. It considers the inverter Volt-Ampere rating, that is, voltage and current limits. Some examples are reported. After a preliminary analytical design, finite element analysis is adopted and linked to a multi-objective optimization. Finally, a prototype is manufactured and tested to validate the predicted results.
