A multiple output synchronous generator in accordance with the instant invention comprises a stator having a first stator winding having a number of poles p and a second stator winding having a number of poles 2*p*n where p and n are any whole numbers, the first and second stator windings being wound utilizing a 60.degree. phase belt winding configuration such that the first stator winding is magnetically decoupled from the second stator winding preventing interaction therebetween. The generator additionally comprises a rotor rotatably disposed within the stator defining an airgap therebetween. The rotor has a first field winding of a first polarity and a second field winding having a second number of windings wound thereon for generating a flux across the airgap such that the flux induces a voltage in the first and second stator windings. These first and second field windings are configured such that the flux generated in the airgap comprises a fundamental component and an even harmonic component of substantially equal magnitude. The winding configuration of the stator and rotor insure that only the fundamental flux component and odd harmonics induce a voltage in the first stator winding, and only the even harmonic component and even harmonics induce a voltage in the second stator winding. The magnetic decoupling of the first and second stator windings ensures that harmonic distortion induced in the second output by external equipment powered thereby is not reflected in the first output, thereby maintaining a "clean-bus" for use by utilization equipment sensitive to such distortion.
