Abstract :
This paper examines the influence of slot geometry in means of the impact of pole shoes at the stator teeth on ac armature losses in concentrated windings of Interior Permanent Magnet (IPM) synchronous machines. It is shown that the rotor position as well as the stator teeth geometry affects the ac armature losses in the concentrated windings. Here a configuration without a pole shoe tends to have higher losses due to the stronger effect of the rotor stray flux onto the stator windings.
