🔍 Key Concepts

• Cooling and ventilation requirements for electric motors • Effect of ambient temperature vs internal heat generation • Common causes of overheating in DC motors

💭 Think About

• Which choice directly restricts the motor’s ability to get rid of heat? • Which option would actually tend to make the motor run cooler rather than hotter? • Which choices describe electrical faults that usually cause loss of power rather than simple overheating of an otherwise running motor?

✅ Before You Answer

• Identify which option affects airflow around/through the motor • Eliminate any option that would normally lower temperature instead of raise it • Consider which conditions are commonly checked first when a motor casing feels abnormally hot in service
