We have designed a permanent magnet assisted synchronous reluctance machine (PMa-SynRM) for applications requiring robustness and cost effectiveness. To keep costs low, we use ferrite magnets for magnetic excitation. To achieve efficient torque behavior, we considered various design aspects in the development of the PMa-SynRM. Our PMa-SynRM features magnets placed in the stator only, and not mounted on the rotor. This paper presents the modelling and simulation of the magnetic behavior and the geometric optimization of the PMa-SynRM. The rotor geometry was investigated in particular detail, using two- and three dimensional finite element (FE) simulations. We performed no-load and load measurements and applied system analysis to identify the torque characteristic. |
