Power hand tool

摘要

A power hand tool includes a body and an electric motor in the body and having a shaft for driving a connector for connecting and driving a cleaning/polishing implement. An enclosure encloses the motor for protection against intrusion of a liquid, and includes a thermally conductive end cap that is exposed outside of the body. A thermal conductor in contact with a metal casing of the motor and the end cap conducts heat from the motor to the end cap for heat dissipation.
