چکیده :

Fast calculation is the major advantage of the subdomain analytical modeling of electrical Machines when compared to Finite Element modeling (FEM). However, for some permanent magnet (PM) arrangements inconsistent to a single coordinate, the FEM is more accurate and so more trusted. In this research a fast subdomain approximation of brushless electrical machines with spoke-hub PMs on rotor is developed for calculation of the rotor and stator fields and the resulted torque. Comparison with FEM results shows that for common arrangements of rectangle and arc-formed PMs, the two-dimensional (2-D) analytic modeling can accurately calculate electromagnetic quantities and the electromagnetic torque.
