Abstract

A power tool includes a housing formed of two half-housings and an end cap. A stator is mounted in the housing, and a rotor including a rotor core and a permanent magnet is mounted in the stator core. A rotary shaft having an axis of rotation extending in a front-rear direction supports the rotor core. Insulators are mounted at front and rear axial ends of the stator core, a planetary gear is mounted forward of the rotor core and a handle extends from the housing. The front insulator includes two recesses, and a first portion of each recess opens radially and a second portion of each recess opens axially rearward. Portions of the stator core cover the recesses, and projections extend from the housing and respectively mate with the recesses.
