Abstract
In synchronous and induction machines, low torque oscillations and low noise excitation can be reached by choosing a skewed design. In practice, the skew angle of the slot openings is about one rotor or stator slot pitch. In analytical calculation, the skewing is considered as reduction of the magnetic linkage between stator and rotor winding. The advantage of skewing is to eliminate the magnetic linkage between stator and rotor winding for the slot harmonics in the air-gap field which might produce synchronous or asynchronous harmonic torque components as well as magnetic noise. It is often unknown that, besides these positive effects, skewing leads to a dependency of the fundamental amplitude of the air gap field in axial direction that influences the iron losses in the stator core. In this paper, this influence of skewing on the iron losses is discussed and quantified for an example.
