Speed control of DC Shunt motor (Armature control and field control method) practical experiment

For circuit connections go to • Swinburne's test on DC...
Speed control methods of shunt motor:
1. Armature rheostat control.
2. Field flux control.
Armature rheostat control:
Speed control is achieved by adding an external resistance in the armature circuit. This
method is used where a fixed voltage is available. In this method, a high current rating
rheostat is required.
Field flux control:
Speed control by adjusting the air gap flux is achieved by means of adjusting the field
current i.e., by adding an external resistance in the field circuit. The disadvantage of this
method is that at low field flux, the armature current will be high for the same load. This
method is used to run the motor above its rated speed only.

Totally understandable 👍,
Thank you sir !

[@vedantupadhyay5927]

Thank you sir , totally understand the practical 🙏🏻

Very nice..... amazing 🤩👍🏻

Good bhayya

[@tapasmishra3198]

In Field control method when resistance increase then speed is inrcease
Is armature control method same or not?

[@fasihakhanum4213]

Good

[@gksah2493]

there is a mistake in graph of field control method
it should hyperbolic not linear

[@honeystazz9777]

why are we multiplying the the readings by 2

[@PAPU_127]

Because here sir use voltage is 0-150 v but in the given circuit we use range as 0-300v so only we multiply the readings by 2
