AC motor nameplate: service factor and insulation class decoded

NEMA motor nameplates list service factor as a horsepower multiplier (commonly 1.0 for totally enclosed motors and 1.15 for open drip-proof types) and insulation class as a thermal limit (A 105°C, B 130°C, F 155°C, H 180°C). These two fields together fix continuous overload capability and winding li
