Claim 7:
8. The energy conversion device according to claim 5, wherein an angle of the resultant current vector of at least one pair of the winding units in the L sets of the winding units with respect to the direct axis of the synchronous rotating reference frame is a variable value; an angle of one of the pair of the resultant current vectors with respect to the direct axis of the synchronous rotating reference frame is θL/2-1=2 πf1t+θL/2-0; an angle of the other of the resultant current vectors with respect to the direct axis of the synchronous rotating reference frame is θL/2-1=2 πf1t+θL/2-0; f1 is a change frequency of the angle of the resultant current vector with respect to the direct axis of the synchronous rotating reference frame; θL/2-0 is an initial angle of the angle of one of the pair of the resultant current vectors with respect to the direct axis of the synchronous rotating reference frame; and t is a time.
