Starting methods of a DC motor |

Basic operational voltage equation of a DC motor is given as E = E b + I a R a and hence, I a = (E E b) / R a Now, when the motor is at rest, obviously, the back emf E b = 0. Hence, armature current at the moment of starting can be given as I a = E / R practical DC machines, armature resistance is basically very low, generally about Ω.Therefore, a large current flows through the ...

DirectCurrent Machines

• DC machines can develop rated torque at all speeds from standstill (lockedrotor) to rated speed. DC machines are easier to analyze than their AC counterparts, although their construction is made rather complex by the fact that they need a commutator, which reverses the direction of currents and fluxes to produce a net torque. • DC motors are used in a wide variety of industrial drives ...
