Abstract
An end cap 16 for a miniature electric pmdc motor has two fixed brush cages 36, 38 moulded integrally with the end cap and two separate brush cages 40, 42 which are attached to the end cap 16 during the assembly process. The angular separation of the fixed brush cages 36, 38 and the separate brush cages 40, 42 is determined during assembly so that the angle can be adjusted to suit the application of the motor.
