In a loaded DC motor, if the bushes are given a shift from the inter p...
Explanation:
Effect of shifting bushes in a loaded DC motor:
When the bushes in a loaded DC motor are given a shift from the inter-polar axis in the direction of rotation, it affects the commutation process in the motor.
Commutation process:
Commuation is the process of reversing the direction of current in a coil at the moment it passes from one pole to another. It ensures that the torque produced by the motor remains in the same direction throughout the rotation.
Impact on motor speed:
- Shifting the bushes in the direction of rotation will cause poor commutation.
- Poor commutation results in sparking at the brushes, which can lead to increased friction and reduced efficiency.
- As a result, the motor speed will decrease due to increased friction and inefficiency.
Conclusion:
Therefore, in a loaded DC motor, if the bushes are given a shift from the inter-polar axis in the direction of rotation, the communication will decrease and the speed of the motor will increase.
