Question 253Electricity & Electronics - QMED

The correct answer is C) cool the motor with portable blowers and fans. When an electric motor is overloaded, the increased current draw can cause the motor to overheat, potentially leading to damage. Cooling the motor with portable blowers or fans is the recommended action to prevent this. This helps dissipate the excess heat generated by the overload, allowing the motor to continue operating safely until the emergency situation has passed. The other options are not appropriate: A) Holding thermal overload relays open would bypass the motor's built-in protection, risking damage. B) Increasing residual magnetism would not directly address the overheating issue. D) Injecting CO2 into the windings is not a practical or effective cooling method in an emergency.
