摘要： A commutator for electrical machines and a method of manufacture of the commutator is disclosed which consists of a lamination assembly held together by a pair of shrink-rings. One of the rings serves to support the commutator on a commutator hub and comprises first and second ring portions having between them a decoupling portion. The first ring portion is in the form of a shrink-ring and holds together the lamination assembly. The second ring portion is secured to the commutator hub. The other shrink-ring also holds together the lamination assembly. In the method of manufacture of the commutator, both the first and second ring portions are simultaneously shrunk on to the lamination assembly and commutator hub respectively.
