Abstract:
In this thesis, no-load and full-load performance of Permanent Magnet Vernier Generators (PMVGs) is investigated in fully-aligned condition and under different types of mechanical faults. The studied mechanical faults are Static Eccentricity (SE), Dynamic Eccentricity (DE), Inclined Rotor (IR), and Run-out (RO). Furthermore, an analytical model is also developed to calculate the permeance of the air-gap and the induced voltages in the health machine and under studied mechanical faults. Then, 2-D and 3-D non-linear, time stepping finite element method is utilized for performance evaluation of the generator in no-load and full-load (with resistive, inductive and capacitive loads). In continue, the performance of a conventional outer rotor permanent magnet generator, considering constant dimensions, constant PM, copper and iron usage is compared with the studied PMVG. The performance of two generators are studied in fully-aligned condition as well as under SE and DE. Finally, a small PMVG is designed, optimized and built to meet power concussion requirements of road speed cameras
