In a three-phase motor, the part that field coils interact with is known as?

In a three-phase motor, the part where the field coils interact is known as the stator. The stator is the stationary component of the motor and is equipped with winding coils that are energized to create a rotating magnetic field. This magnetic field interacts with the rotor (the rotating part of the motor), causing it to turn.

The design and function of the stator are critical in producing the necessary magnetic field for motor operation. The interaction between the field coils on the stator and the rotor is what ultimately allows for the conversion of electrical energy into mechanical energy. This is fundamental to the operation of all three-phase motors.

The other components mentioned, such as the commutator and the rotating armature, play roles in different types of motors, particularly in DC motors and synchronous motors respectively, but they do not pertain to the specific interaction that occurs in a three-phase motor’s stator. The term "induction coil" is not commonly used in the context of three-phase motors, further distinguishing the role of the stator as the primary component involved in the interaction with the field coils.
