Which component in an electric motor is mainly responsible for generating rotational motion?

The rotor is the component in an electric motor that is primarily responsible for generating rotational motion. It is the rotating part of the motor, typically situated within the magnetic field created by the stator. When electric current flows through the motor's windings, it interacts with this magnetic field, causing the rotor to turn. The design and construction of the rotor allow it to efficiently convert electrical energy into mechanical energy, which is the essence of how motors operate.

In electric motors, the rotor's motion is often aided by other components, such as the stator, which provides a stationary magnetic field. However, it is the rotor that directly engages with this field to create the rotational action. The commutator can help in switching the current direction in certain types of motors (like DC motors) to maintain rotation but does not generate motion by itself. The inductor may be involved in the motor's operation but does not specifically contribute to the generation of rotational motion. Thus, the rotor stands out as the essential part that achieves this primary function in electric motors.
