Electrical Engineering XYZ MCQs

In a dc machine 4 pole lap winding is used. The number of parallel paths are:

  1. 4
  2. 1
  3. 2
  4. 8

Correct answer: 1. 4

Explanation:

In a DC machine with a 4-pole lap winding, the number of parallel paths is determined by the number of parallel conductors in each armature slot.

The formula for calculating the number of parallel paths (P) in a DC machine with lap winding is given by:

P = Z/2P

Where:

  • Z is the total number of armature conductors
  • P is the number of poles

In this case, the question specifies a 4-pole lap winding. Since lap winding means that each pole has two parallel paths (coil sides), the value of P is 2.

Therefore, the correct answer is:

P = Z/(2*2) = Z/4​

So, in a 4-pole lap winding, the number of parallel paths is 4.

Henceforth, the correct option for this Electrical Engineering XYZ MCQ is: 4
