Basic Construction: A universal motor, analogous to a series DC motor, features stator and rotor windings connected in series. It is capable of operation on both AC and DC power supplies. When powered by AC, current traverses both the stator and rotor windings. As both field and armature currents reverse concurrently, the torque direction remains constant. Torque, which drives rotation, is generated by the interaction between the magnetic field produced by the stator and the current within the rotor winding. This motor operates at exceptionally high speeds and is frequently employed in portable power tools and household appliances.
