What type of starting mechanism might a shaded-pole motor use?

A shaded-pole motor typically does not use any of the starting mechanisms listed in the choices provided. Instead, it relies on the principle of shading coils placed around the pole to create a rotating magnetic field that allows for starting and running. This motor type is designed to operate in a simple manner without the complex starting mechanisms found in other motor types, such as capacitor-based or electromagnetic starters.

Shaded-pole motors are commonly used in applications such as fans and small appliances because they are easy to construct and are cost-effective. Their design relies on the basic magnetic principle of shading to achieve motor operation, which distinguishes them from other motors that utilize specific starting methods to enhance performance and starting torque.
