What is the difference between the excitation winding and armature winding of AC motor?
The motor defines the armature as the main power loop of the motor. You just have to think about the power of the stator circuit or the power of the rotor circuit. That big one is the armature". Power is voltage X current. Only synchronous generator and synchronous motor have excitation winding and armature winding. In general, AC induction motors do not have field windings. The asynchronous motor is divided into two major categories, squirrel cage and winding. The stator winding structure is the same. The squirrel cage rotor is a squirrel cage, and the winding rotor is a coil (which can be changed by an external device to change the rotor impedance). The so-called armature winding is the main power circuit of the motor". Rotor and stator coil which power is larger, which is "armature", needless to say, most of the stator coil is armature winding".
The field winding is winding excitation magnetic field and armature winding is winding AC output power, DC excitation for synchronous generator, the rotor winding is winding of generator stator winding and armature winding is the generator.
Only synchronous generator and synchronous motor have excitation winding and armature winding. In general, AC induction motors do not have field windings.
