Universal motors are a type of motor that can operate on both AC and DC supplies. They are structurally similar to a DC series motor. In these motors, the stator (field) winding and the rotor (armature) winding are connected in series.
This series connection causes the same current to flow through both windings. Since both the magnetic field (produced by the stator) and the armature current reverse simultaneously with AC, the direction of torque remains the same, enabling the motor to run on an AC supply.
The key point is that in a series configuration, torque is proportional to the square of the armature current, which results in very high starting torque, making universal motors ideal for appliances like mixers, drills, and vacuum cleaners.
