A crucial factor to consider when planning maintenance of high-voltage (HV) motors and generators, especially those in critical industrial applications, is the life expectancy of the stator windings.

A small 0.75 horsepower, 4-pole, 460 V, Class F AC motor (Figure 1) was chosen for the model rewind. This motor was selected as it is compact in size and has lightweight dimensions to allow easy ...

Historically, generator inspections require rotor removal (Figure 1). There’s a significant level of risk during this process due to possible generator damage during the disassembly, and it also ...
