Abstract
This paper examines the iron loss characteristics of a high-flux interior PM machine. This was designed as a concept demonstrator for a 6kW automotive alternator and has a wide field-weakening range. Initial experimental tests showed a high iron loss during high-speed field-weakening conditions. This paper examines the causes of this high iron loss using finite-element simulations and experimental tests. It was found that the high iron loss was due to high harmonic airgap flux density components during field-weakening. Means to reduce these losses are discussed.
