Study of Characteristics for D.C. Series Motor Using Mechanical Loading (Brake Arrangement)

Generally, three characteristic curves are considered important for DC motors whichare, (i) Torque vs. armature current, (ii) Speed vs. armature current and (iii) Speed vs. torque.These are explained below for D.C. Series Motor.These characteristics are determined by keeping the following two relations in mind.Ta ∝ ɸ.Ia and N ∝ Eb/ɸThese above equations can be studied …
