Abstract

A power tool is provided including a motor housing; a transmission housing disposed adjacent the motor housing with a gap therebetween; an electric motor including a rotor and a stator mounted within the motor housing; and an intermediate housing disposed between the electric motor and the transmission mechanism. The intermediate housing includes a back wall extending radially adjacent an axial end of the stator and having a through-hole therein through which the motor spindle extends; side walls extending axially from an outer circumference of the back wall internally of the motor housing; and one or more external walls extending substantially-radially outwardly from axial end of the one or more side walls to fill a gap formed between the transmission housing and the motor housing in the axial direction.
