(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

the speed of dc motor is given by N=60(A/p)(V-Ia*Ra)/(Z*phi)

where,

A=no. of parellel paths

P=no of poles

V=voltage applied at dc motor

Ia= armature current

Ra=armeture resistence

Z= total no. of armature conductor

phi=flux per conductor.

but if some how we stop the dc motor by appling some force then "speed of it would change"? i.e. the enduced emf will change.

is it corect???????????
