Abstract
This paper presents a clamping plate loss model based on surface impedance boundary conditions. The clamping plate surface is discretized using a single loop of nodes. By making a clever choice of boundary conditions instead of modeling an entire pole pitch and only considering the fundamental temporal and spacial harmonic of the field normal to the clamping plate surface, the number of nodes (and elements) required is reduced to around 100, making the proposed method computationally inexpensive. However, the presented loss model requires the knowledge of the flux density normal to the clamping plate, making it only useful in situations where a fast method of obtaining the normal flux density distribution is available. In this paper, three-dimensional time step FEA is used to both validate the proposed loss model and assess the impact of assumptions made in its derivation. For the geometry investigated in this paper, only 61 nodes were required leading to a computing time of 20 ms with an error of 3 % when compared to time step 3D FEA.
