An AC series motor is a type of electric motor that can operate on alternating current (AC) supply while maintaining characteristics similar to a DC series motor. Because of its high starting torque and compact design, it is widely used in household appliances and power tools.If you are an electrical engineering student, technician, or someone interested in motor technology, understanding the AC series motor diagram and its working principle will help you grasp how this motor performs efficiently under AC supply.

What is an AC Series Motor?An AC series motor is essentially a modified DC series motor designed to operate on AC supply. In this motor, the field winding and armature winding are connected in series, meaning the same current flows through both.However, since AC current reverses direction periodically, certain design modifications are made to reduce losses and improve performance when running on AC.
