The motor leads in the terminal box of an AC motor originate at which part?

• A. Rotor
• B. Stator
• C. Commutator
• D. Frame

Answer: (B)

The motor leads in the terminal box of an AC motor originate from the stator. The stator is the stationary part of the motor and contains the winding that generates the magnetic field necessary for motor operation. When alternating current (AC) is supplied to the stator windings, it creates a rotating magnetic field. This rotating field interacts with the rotor, which is the moving part of the motor. In an AC motor, the connections for power supply are typically made at the stator windings, and these leads are brought out to a terminal box for easy connection to the electrical supply. Understanding this connection is fundamental, as it helps in troubleshooting and maintenance of AC motors, ensuring that technicians can identify the source of electrical supply correctly.
