Generator common core winding

A variable frequency generator, comprising:

• a housing;
• a shaft rotationally received in the housing, the shaft defining a rotational axis;
• a rotor disposed on the shaft so as to be rotationally linked to the shaft;
• a stator at least partially surrounding the shaft and defining a plurality of slots;
• a first set of stator windings including a first subset in a first configuration and having a first common point of connection and a second subset in a second configuration having a second common point of connection different from the first common point of connection;
• and
• a second set of stator windings including a first subset in a third configuration and having a third common point of connection and a second subset in a fourth configuration having a fourth common point of connection different from the third common point of connection,
• wherein:
• the windings of the first subset of the first set of stator windings share a common slot of the plurality of slots of the stator with the windings of the first subset of the second set of stator windings;
• the windings of the second subset of the first set of stator windings share a common alternative slot of the plurality of slots of the stator with the windings of the second subset of the second set of stator windings;
• current of the windings of the first subset of the first set of stator windings and the windings of the first subset of the second set of stator windings flows with a first phase shift;
• and
• current of the windings of the second subset of the first set of stator windings and the windings of the second subset of the second set of stator windings flows with a second phase shift, and wherein the second phase shift is different from the first phase shift;
• and
• the first common point of connection is connected to the third common point of connection and the second common point of connection is connected to the fourth common point of connection, the first common point of connection does not share a connection to the second common point of connection.
