What percentage of the motor's voltage rating MUST a motor supply voltage be within?

• A. 1
• B. 3
• C. 5
• D. 10

Answer: (D)

A motor's supply voltage must be within a certain percentage of its voltage rating to ensure optimal performance and prevent potential damage. The correct answer is based on industry standards which state that a motor should receive a supply voltage within 10% of its rated voltage. Operating a motor outside this range can lead to issues such as overheating, inefficient performance, and a reduction in the lifespan of the motor. If the voltage is too low, the motor may not start or run efficiently, leading to increased current draw and potential stalling. Conversely, if the voltage is too high, this can result in excessive heat buildup and component failure. Thus, by adhering to this 10% tolerance, you help ensure that the motor operates effectively and reliably, thereby maintaining safety and efficiency in electrical systems.
