What component of a motor is responsible for providing torque or power to perform mechanical work?

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

Answer: (B)

The rotor is the component of a motor that is responsible for providing torque or power to perform mechanical work. When electricity flows through the motor, it creates a magnetic field that interacts with the rotor. This interaction generates rotational motion, which is the basis for producing torque. The rotor represents the moving part of the motor that converts electrical energy into mechanical energy, enabling it to perform tasks or drive machinery.

Understanding the function of the rotor also highlights the importance of its design and material, as these factors affect how efficiently it converts electrical energy into motion. By producing the necessary torque, the rotor plays a crucial role in the overall operation of the motor, allowing it to accomplish various mechanical tasks effectively.
