What is the purpose of a commutator?
Understand the Problem
The question is asking about the function or role of a commutator, which is a concept in mathematics and physics, particularly in the context of group theory and quantum mechanics. The answer will likely explain how commutators are used to measure the difference between two operations or to understand the behavior of certain algebraic structures.
Answer
To ensure that the current in the rotor windings flows in the same direction and the proper coil on the rotor is energized.
The final answer is to ensure that the current flowing through the rotor windings is always in the same direction, and the proper coil on the rotor is energized in respect to the field coils

More Information
A commutator is a rotary electrical switch that periodically reverses the current direction between the rotor and the external circuit, ensuring that the proper electromagnets are energized at the right time.
Tips
A common mistake is confusing the commutator's function with that of a rectifier, which also deals with current direction but is not typically used in motors.
