What happens when the motors are operated beyond their rated capacity?

• A. They run more efficiently
• B. They may draw excessive current
• C. They will reduce heating
• D. They operate at lower speeds

Answer: (B)

When motors are operated beyond their rated capacity, they may draw excessive current. This occurs because when a motor is pushed to perform beyond its design specifications, it requires more electrical current to meet the increased workload. This can lead to overheating due to the increased electrical resistance and generation of heat within the motor's windings. The additional heat can damage the motor's insulation and other components, leading to premature failure or burnout. The risk of excess current flow also affects the electrical system as a whole, potentially leading to tripping of circuit breakers and posing risks to connected equipment. Hence, it's crucial to operate motors within their specified ratings to ensure safety, efficiency, and longevity.
