Description

Hence, the magnetic field of an alternator is always rotating inside the stator, whereas, the magnetic field for a generator is fixed. The armature is the rotating coil or series of coils in an electric motor. When the armature is stationary it becomes easy to produce voltage(low voltage) excitation to the rotor through the slip rings. You would choose a generator when more electricity is needed because they produce voltage throughout the entire device without stopping. You can use a generator to charge a battery when it’s completely drained as well. For this reason, we see generators as the best possible option as a power backup for homes and RVs. These are cut out for the big jobs because the output current is constant, and it generates both Alternating current and Direct Current.
