Abstract

A power tool includes a housing and an electric motor assembly supported in the housing. The electric motor assembly includes a stator core and a circuit board proximate an end of the stator core. The circuit board includes a heat-generating component facing away from the stator core. The electric motor assembly also includes an end cap coupled to the stator core and in thermal contact with the heat-generating component as a heat sink to remove thermal energy from the heat-generating component.
