AC ROTATING ELECTRIC MACHINE STATOR AND WINDING STRUCTURE OF AC ROTATING ELECTRIC MACHINE STATOR

摘要

PROBLEM TO BE SOLVED: To solve the problem in the connection of conventional segmented winding that there is a very large potential difference between the reverse and normal phase coils inserted into the same slot.;SOLUTION: In a segmented wound motor with the number of pole pairs of 8, the phase difference between the end of reverse phase winding and the start of normal phase winding is controlled to a value equivalent to 80°± equivalence to one magnetic pole, in terms of the mechanical angle. Thus, the potential difference between reverse phase winding and normal phase winding in the same slot can be reduced to approx imately, and 75% of the potential difference between X1 terminal and X1' terminal at a maximum.;COPYRIGHT: (C)2003,JPO
