What is the potential consequence of connecting a motor to an inappropriate power supply?

• A. Enhanced performance
• B. Increased efficiency
• C. Motor damage
• D. Lower energy costs

Answer: (C)

Connecting a motor to an inappropriate power supply can lead to motor damage, which makes this answer the most accurate choice. When a motor is supplied with voltage or current that does not match its specifications—such as the voltage being too high or too low, or the phase being incorrect—it can result in excess heat generation, inadequate performance, or complete failure of the motor. Motors are designed to operate within a specific range of power supply parameters. If these parameters are exceeded or not met, the motor may overheat, leading to insulation breakdown, bearing damage, or even catastrophic failure. This type of damage often requires costly repairs or complete replacement of the motor. In contrast, the other options refer to outcomes that are typically favorable and would not occur if a power supply is inappropriate. Enhanced performance and increased efficiency would only be observed if the motor received the correct power supply. Similarly, lower energy costs are not a consequence of misapplying power supplies, as inefficient operation due to incorrect supply settings generally leads to higher energy consumption and wasted resources.
