Disadvantages of armature speed control for a DC motor include complexity of control circuitry, increased maintenance due to wear on the brushes and commutator, and limited speed range compared to field control methods. Additionally, armature control can result in lower efficiency and poor performance at low speeds.

speed of a dc motor can be varied by mainly two methods:- 1)field control method 2)armature control method further , field control method can be divided in 3 parts:- 1)field rhestat control method---speed variation is acomplished by means of a variable resistance inserted in series with shunt field 2)reluctance control method---by changing the reluctance of magnetic circuit by choosing right material.. 3) field voltage control method-requires variable field voltage supply. and armature control method can be divided in 3 parts :- 1)armature resistance control---variable resisitance connected in series with armature 2)shunted armature control. 3)armature voltage control. ------------mrityunjay pandey (kiit university ,btech 2nd year)
what are the advantages and disadvantages of a eureka can
there are two methods i.e armature control method and field control method....
The distillation method's advantages are that it will make a pure result. The disadvantages are that the method is time consuming and is not cheap. The distilled method as a result is avoided unless needed.

this method is rediculous
Everything has its advantages and disadvantages both, so accept these logics and their aspects in your life.
