Share:
- 1In a stationary armature configuration, the exciting field current is relatively high; therefore, the slip rings and brush gear need to be of heavy construction.✓
- 2The stationary armature is housed in a stationary frame that provides a large surface area for efficient cooling.
- 3The stationary armature does not rotate, making it less prone to mechanical wear and tear, resulting in higher reliability.
- 4The stationary armature is responsible for producing the stator magnetic field that interacts with the rotor magnetic field to generate torque.
Correct answer
In a stationary armature configuration, the exciting field current is relatively high; therefore, the slip rings and brush gear need to be of heavy construction.
