Which of the following comes under the category of single-phase commutator motors?

• A. Shaded pole motor
• B. Resistance start motor
• C. Universal motor
• D. Capacitor start motor

Answer: (C)

The commutator is a feature of d.c.motors. But a.c. motors having wound rotor with brushes and commutator arrangements, are called commutator motors that work on single-phase a.c. supply. The commutator arrangement present in these motors is similar to the armature of a d.c. motor.E.g. of single-phase commutator type induction motor is
Repulsion Motor
Repulsion-Induction Motor
AC Series Motor
Universal Motor
