Damage to commutator segments
Damage to commutator insulation
motor may result in A. Damage to commutator segments B. Damage to commutator insulation C. Increased power consumption
All of the above
Answer is Right!
Answer is Wrong!
The correct answer is: D. All of the above
Sparking at the commutator of a D.C. motor may result in:
- Damage to commutator segments: The sparking can cause the commutator segments to become pitted and worn, which can lead to increased resistance and decreased efficiency.
- Damage to commutator insulation: The sparking can also cause the commutator insulation to break down, which can lead to arcing and further damage to the commutator.
- Increased power consumption: The sparking can cause the motor to draw more current, which can lead to increased power consumption and decreased efficiency.
In addition, sparking can also cause noise and vibration, and can be a safety hazard. Therefore, it is important to keep the commutator clean and free of dirt and debris, and to replace worn or damaged commutator segments as necessary.
