According to NEMA, what is motor 'design'?

Explanation:
Motor design, per NEMA, is about the motor’s performance characteristics—the torque it can develop and the current it draws as it starts and runs. This describes how the motor behaves under load: the starting torque, starting current, and the full-load current at operating speed. These electrical and mechanical performance traits determine how well the motor matches a given load, drive, and power supply. Physical attributes like the color of insulation, mounting style, or frame size aren’t part of design—they’re about construction, mounting, or size, not how the motor performs.
