Advantages * The series motor has the highest starting torque for a given power rating. When the motor is overloaded, the speed drops and the torque increases. While delivering high torque during an overload, the series motor draws less current rotating magnetic field inside the motor whereas an asynchronous motor rotates slower compared to the rotating magnetic field.

A DC series motor has all the 6 fundamental components-axle, rotor (armature), stator, commutator, field magnet(s) and brushes-that are present in a generic DC motor. The motor casing where two or more electromagnet pole pieces are housed forms the stationary part of the motor, the stator. The configuration of a universal motor is similar to a DC-series motor. Since the stator is now subject to an alternating magnetic field it should be laminated to reduce iron losses (in contrast to the DC-series motor). To limit sparking of the collector special high resistance brushes are used.
