Universal Motor - construction, working and ...

A universal motor is a special type of motor which is designed to run on either DC or single phase AC supply. These motors are generally series wound (armature and field winding are in series), and hence produce high starting torque (See characteristics of DC motors here). That is why, universal motors generally comes built into the device they are meant to drive.

Starting methods of a DC motor - electricaleasy.com

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 a.In practical DC machines, armature resistance is basically very low, generally about 0.5 Ω.Therefore, a large current flows through the ...
