What is a Rotating Magnetic Field?Rotating field definitionWhen a three-phase power supply is applied to a three-phase distributed winding in a rotating machine, a rotating magnetic field is generated.Although the vector sum of the three currents in a balanced three-phase system is zero at any moment, the resultant magnetic field produced by these currents is not zero. Instead, it has a constant non-zero value that rotates over time.The magnetic flux produced by the current in each phase can be
