The magnetic pole that projects above the surrounding stator core in a shaded-pole motor is known as the _________ pole.

• A. auxiliary
• B. shaded
• C. salient
• D. main

Answer: (C)

In a shaded-pole motor, the magnetic pole that extends above the surrounding stator core is referred to as the salient pole. This design feature is critical for the functioning of the motor, as it creates a stronger magnetic field at the pole face, which enhances the motor's ability to generate torque. The term "salient" specifically indicates that the pole is prominent and stands out compared to the rest of the stator structure. This characteristic aids in producing the necessary rotating magnetic field required for motor operation. The other terms, although related to motor operation, do not accurately describe the function and design of the pole in question within a shaded-pole motor. Understanding the distinction of the salient pole is key to grasping how shaded-pole motors work and their construction dynamics.
