What is the primary function of the rotor in a single-phase motor?

The primary function of the rotor in a single-phase motor is to induce motion through the magnetic field. In a single-phase motor, the rotor is placed within the stator, which produces a rotating magnetic field. This magnetic field interacts with the rotor's conductors, leading to induced currents that create a force. As a result, the rotor starts to turn, converting electrical energy into mechanical energy. This motion is fundamental for the motor's operation, allowing it to perform various mechanical tasks, such as driving pumps, fans, or other machinery.

In contrast, while the rotor interacts with a magnetic field, it does not itself create the magnetic field (which is the role of the stator). Providing electrical feedback to the stator is not a function of the rotor; this is more relevant in feedback systems for controlling motor performance. Additionally, housing electrical connections pertains to the framework or enclosure of the motor rather than the rotor's purpose. Therefore, the focus on the rotor's role in inducing motion through the magnetic field is what accurately defines its primary function.
