1: What is the primary function of a DC motor in electrical
systems?--- correct answer ---
The primary function of a DC motor is to convert direct current
electrical energy into mechanical energy.
2: What are the main components of a DC motor?--- correct answer
---
The main components of a DC motor include the stator, rotor (or
armature), commutator, brushes, and bearings.
3: How does a commutator function in a DC motor?--- correct
answer ---
A commutator reverses the direction of current flow through the
motor windings, ensuring that the torque generated by the motor
remains in the same direction.
