What is parallel path in dc machine?
This describes the way the machine's armature conductors are connected relative to each other and to the number of poles. The two basic ways of connecting these conductors are called 'lap' and 'wave', but it gets more complicated, because these, in turn, can be connected 'simplex', 'duplex', 'triplex', etc.For lap windings, if there are p poles, then for:simplex: pduplex: 2ptriplex: 3petc.For wave windings, the number of parallel paths are:simplex: 1 x 2duplex: 2 x 2triplex: 3x 2etc.So, for a triplex lap winding machine with six poles, the number of parallel paths will be: 3p =3 x 6 = 18 parallel paths.

The use of composite function in dc machine?
f(x)=3x ,g(x) = x2 find gof(x)
What is the use of interpoles in dc machine?
Interpoles are similar to the main field poles and located on the yoke between the main field poles. They have windings in series with the armature winding. Interpoles have the function of reducing the armature reaction effect in the commutating zone. They eliminate the need to shift the brush assembly.

How does voltage commutation work in DC machine?
In voltage commutation process, the introduction of interpoles between main poles compensate armature mmf and reduces the effect of armature reaction.
What is the important of brush in DC machine?
The slip rings are the most important brush in DC machine.
What is swinburne's test of DC shunt motor?
swinburne's test on dc shunt machine is to predetermine the efficiency of the dc machine , but it is not accurate it is just like estimation of efficiency of dc shunt machine when it is run as a motor and a generator............................

How many poles are within a DC motor?
It depends on the motor. They can be purchased with different numbers of poles. The number of poles mainly changes the speed of the motor.
