The dynamic and transient performance analysis of a three-phase interior rotor concentrated winding permanent magnet synchronous generator (CW-IPMSG) with was presented. In this paper. The study was done in direct-phase variables concentering only the fundamental magneto-motive force (MMF). The machine’s inductance was determined using winding function theory (WFT). The derived inductance was used to determine performance characteristics of the machine’s variables such as phase current, load current and electromagnetic torque. The study was validated in MATLAB/Simulink to observe the performance of the characteristics of the generator. The study was carried out at no-load condition, under load perturb, as well as increase and decrease of capacitor. It was observed that the permanent magnet synchronous generator had slightly better output performance with capacitor assistance.
