How to Evaluate Back Pitch for DC Machine?

Back Pitch for DC Machine evaluator uses Back Pitch = ((2*Number of Slots)/Number of Poles)+1 to evaluate the Back Pitch, The Back Pitch for DC Machine formula is defined as the coil advances on the back of the armature. This advancement is measured in terms of armature conductors and is called back pitch. It is equal to the number difference of the conductor connected to a given segment of the commutator. Back Pitch is denoted by Yb symbol.
