  1. Hysteresis Loss
  2. Eddy Current Loss
  3. Mechanical Loss
  4. Temperature Rise

Answer: Option B, Eddy Current Loss

Eddy Current Loss is the reason as to the lamination of armature of DC Motor is used to minimize it.

  • The armature is built up in cylindrical or drum shape high-grade silicon steel in the form of lamination. 
  • So when lamination is used, the circular path of Eddy Current is terminated. 
  • Thus, the heating and damage to the armature are reduced by lamination.

Summary:

The Armature of DC Motor is Laminated to Minimise

The Armature of DC Motor is Laminated to Minimise the Eddy Current Loss. Eddy's current loss is directly proportional to the area of the armature or the path of motion.
