What is typically the result of connecting an AC induction motor incorrectly?

  1. The motor will operate normally

  2. The motor may overheat

  3. The motor will reverse direction

  4. The motor will produce no sound

The correct answer is: The motor may overheat

Connecting an AC induction motor incorrectly can lead to overheating due to several factors. One significant issue is that improper connections may cause an imbalance in the electrical supply, which can result in increased current draw. This excessive current can generate more heat within the motor's windings than it is designed to handle, leading to overheating. Additionally, if the motor is underloaded or overloaded as a result of incorrect wiring, it may also fail to operate efficiently, contributing further to heat buildup. While some scenarios might cause a motor to reverse direction or not produce sound, these are less common outcomes of incorrect wiring. It's vital to ensure that the electrical connections adhere to the manufacturer's specifications to prevent such overheating issues.
