Abstract
This paper introduces a new approach for directly calculating the radial flux density in a slotted electrical machine. Through being based on the subdomain approach, it is capable of calculating the air-gap field more accurately than traditional one-dimensional approaches. Contrary to existing subdomain models and finite element analysis, the new approach has the advantage that the cause of certain spatial harmonics of the radial flux density is directly visible. The approach is based on the separation of variables of the vector potential inside the air gap. The radial flux density is calculated at both, the inner and the outer side of the air gap. Using the radial flux density, the circumferential flux density can be calculated. This enables the calculation of the electromagnetic forces including the torque. The approach also encompasses effects due to rotation by assigning each spatial harmonic to a rotational order. This eliminates the need to calculate multiple time steps. Furthermore, the approach provides an extensibility similar to traditional one-dimensional air-gap conductivity based methods.
