Question

Which is the most popular speed control method of DC motor? and why?​

Answer 1

Answer:

Voltage Control Method

Multiple voltage control:

In this method, the shunt field is connected to a fixed exciting voltage and armature is supplied with different voltages. Voltage across armature is changed with the help of suitable switchgear. The speed is approximately proportional to the voltage across the armature

Answer 2

Answer:

HEYY MATE..

Armature control method.

Why do we need a speed control method in a DC motor? See, basically a motor's purpose is to drive any load. Motors are used very widely in factories, traction systems, etc where variable speed is needed as per the requirement. ... In DC motor, we control speed using 1) armature resistance 2) field flux 3) armature voltage.

hope it helps..❤
