Abstract

This work aims to identify and analyze the impact of static and dynamic eccentric tolerances on relevant performance measures of permanent-magnet synchronous-machines with modular stator core (MPMSMs). A 24-slot 28-pole machine with U-shape stator modules is evaluated by means of the finite element method. Also, a non-modular 24-slot 28-pole machine is assessed to compare the sensitiveness of modular vs non-modular PMSMs. Electromagnetic torque, cogging torque, back-emf, and the radial forces acting on the rotor were analyzed. It was found that most of the evaluated performance indices are not influenced by eccentric tolerances. However, a few relevant variables are severely affected, which could potentially endanger the mechanical integrity of the machine.
