Abstract
An electric motor has a rotor and a stator. The stator has an endcap with two brush assemblies, two brush brackets for holding the brush assemblies and two electrical terminals. Each brush assembly is detachably mounted to its brush bracket and has a brush holder, a brush slidably received in the brush holder, a spring for urging the brush out of the brush holder, and a conductive member electrically connecting the brush with a corresponding electrical terminal via a resilient releasable connection.
