Cross-linked commutator having additional parallel paths

摘要

A commutator is provided for a multipole, lap-wound motor wherein N is the number of magnetic poles of the motor and N is an even integer greater than 2. The commutator includes a plurality of commutator bars spaced in a circular arrangement and a connection structure electrically connecting sets of commutator bars which are disposed at an angle of 720 DEG /N therebetween, such that each connected set of commutator bars is electrically isolated from all other sets of connected commutator bars. The number of brushes required for a lap-wound motor employing the commutator may be reduced to two due to the connected sets of commutator bars. <IMAGE>
