In an AC motor, the field winding is a coil of wire that is connected to a power source to create a magnetic field. This magnetic field interacts with the stator windings to produce a rotating magnetic field, which in turn causes the rotor to rotate and drive the motor.
The operation of the field winding type in an AC motor involves passing an alternating current through the field winding to create a magnetic field that rotates at the same frequency as the AC power supply. This rotating magnetic field induces a current in the rotor windings, causing the rotor to rotate and drive the motor.
The field winding type in an AC motor is commonly used in induction motors, where the rotor is not connected to an external power source and relies on the rotating magnetic field to induce current and produce torque. This type of motor is simple, reliable, and cost-effective, making it suitable for a wide range of industrial applications.

Operation of Field Winding Type in an AC Motor
In an AC motor, the field winding is an electromagnetic device that creates a rotating magnetic field. It is typically located on the stator (the stationary part of the motor).
Depending on the type of AC motor, there are two main field winding types:
1. Salient-Pole Field Winding:
- Consists of individual poles mounted on the stator core.
- Each pole carries a coil of wire.
- When an AC current passes through the coil, it creates a magnetic field that alternates in direction.
- The alternating magnetic field induces a rotating magnetic field in the air gap between the stator and rotor.
2. Distributed Field Winding:
- Consists of coils evenly distributed around the stator core.
- The coils are connected in series to form a closed loop.
- When an AC current passes through the coils, it creates a rotating magnetic field that flows continuously around the stator core.
Operation:
- When an AC current is applied to the field winding, it creates an alternating magnetic field.
- This magnetic field interacts with the alternating magnetic field induced in the rotor winding (which is typically on the rotating part of the motor).
- The interaction between the two magnetic fields causes the rotor to rotate.
- The direction of rotation depends on the phase relationship between the AC currents in the field and rotor windings.
Advantages of Field Winding Type:
Salient-Pole Field Winding:
- Simple and robust construction
- Suitable for low-speed, high-torque applications
Distributed Field Winding:
- Produces a smoother rotating magnetic field
- Reduces noise and vibration
- Suitable for high-speed, low-torque applications
The type of field winding used in an AC motor is determined by the desired operating characteristics of the motor, such as speed, torque, and efficiency.
