REDUCTION OF THE ELECTRICAL RESISTANCE FOR AN ELECTRIC MACHINE HAVING WINDINGS ARRANGED IN GROOVES |
摘要 |
<p>An electric machine has grooves and windings, divided into strands, of electrical conductors. At least one strand has a number s of coils connected in series and arranged in the grooves. Each coil has sub-conductors connected in parallel and arranged in bundles. Each bundle is arranged in a groove at a bundle position relative to a deepest possible bundle position in the groove. The positions of all bundles in all coils define a number b of possible bundle positions of the strand. The bundles are interchanged between the coils such that each bundle is arranged in the grooves at least n times and at most n′times at each possible bundle position, wherein n is the integer quotient in regard to the quotient of the number s and the number b, wherein n′=n if s is divisible by b and n′=n+1 if s is not divisible by b.</p> |
