Refurbishment of 8 KVA, 220V Permanent Magnet Generator
A damaged permanent magnet generator (PMG) was totally refurbished by manufacturing rotating permanent magnets, stator core and winding. Magnets had been magnetized with capacitor discharge magnetizer. The winding was globally vacuum pressure impregnated in epoxy resins to achieve high dielectric parameters.
Permanent Magnets Manufacture and Assembly
High speed balancing had been conducted for equal mass distribution, to verify mechanical integrity and as a testimony of qualitative work accomplished. Electrical and dielectric tests had been performed such as insulation resistance (IR), polarization index (PI), DC HV, AC Impedance, Ohmic resistance (OR), surge testing and flux density measurement by Gauss meter.
