I understand that from KVL
e = v -IaRa
e=k(flux)speed
speed=(constant)*(V-IaRa)/flux
But physically what causes the speed to increase?
What force causes the rotor to accelerate?
In fact physically, the rotor is moving because of field flux interacting with armature current's flux.
So physically if I reduce one flux, the speed must reduce, since i have reduced the cause of motion.
