Which starting current characteristic is associated with NEMA Design C motors?

• A. High
• B. Normal
• C. Very low
• D. Low

Answer: (D)

NEMA Design C motors are characterized by a low starting current when compared to other NEMA motor design types. This feature allows them to start smoothly and is particularly beneficial in applications where the electrical supply may be sensitive to high inrush currents. These motors are often used in systems where a gradual startup is important to prevent damage to mechanical components. The low starting current helps reduce wear on these components, and it also minimizes the impact on the electrical supply system. Such characteristics make NEMA Design C motors ideal for applications with varying load conditions or where high starting torque is necessary without a corresponding high inrush current. The other types of starting current characteristics, like high, normal, or very low, do not apply to NEMA Design C motors, as those would describe different motor designs or operational conditions.
