  • 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.How Does a Single Phase Motor Work? Groschopp,May 22, 2013· Single phase motors work on the same principle as 3 phase motors except they are only run off one phase. A single phase sets up an oscillating magnetic field that goes back and forth rather than a rotating magnetic field (see bottom figure). Because of this a true single phase motor has zero starting torque.
