WebSep 17, 2024 · NEMA motors are generally designed with NEMA Design B torque/current characteristics per Part 12 of the MG 1 standard. Those with higher inrush current are Design A. IEC motors in these sizes are IEC Design N and NE, typically having somewhat higher inrush currents than a NEMA Design B motor. WebThe NEMA standard service factor for totally enclosed motors is 1.0. However, many manufacturers build TEFC motors with 1.15 service factors. Capacitors: Capacitors are used on single-phase induction motors except shaded-pole, split-phase and polyphase.
