ABSTRACT:
A moulded plastics material end bracket for a universal motor comprises a U-shaped frame having a base extending between two legs. Brush cages are formed integrally with the two legs and a dust shield in the form of an annular ring formed integrally with the two legs extends axially from the stator core between the stator windings and the commutator and defining a space in which the commutator is located thereby shielding the stator windings from carbon dust generated by the wearing of the brushes on the commutator.
