An overview of analytical methods for magnetic field computation

In this paper, several of analytical methods for modelling the magnetic field are described. These models are used in design routines of the rotating machines, linear motors as well as actuators. Thanks to their high accuracy and low requirements for computation power, they are successfully implemented in designing high precision machines. In order to enlarge the applicability of the methods it is a common practise to combine two or more model such as Magnetic Equivalent Circuit (MEC) and Harmonic Method (HM), Schwartz Christoffel (SC) mapping and Tooth Contour Method (TCM), those combinations turns into so called Hybrid Methods which are also intended to increase the computation speed and results precision.
