A subdomain model for armature reaction field and open‐circuit field prediction in consequent pole permanent magnet machines

Abstract

In this paper, the machine quantity, such as electromagnetic torque, self and mutual inductances, and electromotive force, is analytically calculated for non-overlapping winding consequent pole slotted machine for open-circuit field and armature reaction. The sub-domain approach of (2-D) analytical model is developed using Maxwell's equations and divide the problem into slots, slot-openings, airgap and magnets region, the magnet flux-density is calculated and analyzed for both permanent magnet (PM) and armature current reaction (AR) with radial magnetization pattern. The magnetization surface currents (MSCs) are considered at the borders of iron-pole magnets and the value of MSCs is accurately computed. The result obtained using proposed model compared with that of FEM, (2-D) analytical model required less computation time and achieve higher accuracy of AR and PM.
