What happens if a motor is not properly grounded?

When a motor is not properly grounded, it can pose a significant safety hazard. A proper grounding system is essential for ensuring that any electrical faults or leakage currents are directed safely away from the motor and the operator. Without proper grounding, leakage currents may accumulate, creating a potential for electrical shocks to anyone who comes into contact with the motor or its components. This situation not only endangers personnel but can also lead to equipment damage or unexpected malfunctions.

Understanding the importance of grounding helps emphasize the need for appropriate electrical safety measures in motor control systems. The other options, while they may suggest benefits of a functioning motor, do not accurately reflect the safety risks associated with poor grounding.
