  • The basic idea of an electric motor is to generate two magnetic fields: rotor magnetic field and stator magnetic field and make the stator field rotating. The rotor will constantly be turning to align its magnetic field with that of the stator field. • The 3-phase set of currents, each of equal magnitude and with a phase

  3 1. POWER SOURCES: The common power source in the United States is alternating current, 60 hertz. The power supply may be either single phase or three phase. Generally speaking, single phase is used on electric motors that are less than 1 horsepower. Motors 1 horsepower and larger should be supplied with three phase power if it is available.

  3-phase systems that are roughly balanced (the practical case) can be analyzed profitably by a method called symmetrical components. Here, let us consider only balanced 3-phase circuits (which are the most important anyway). The key to understanding 3-phase is to understand the phasor diagram for the voltages or currents.
