Abstract
A hand held power tool that includes a housing, a power source input configured to receive power from a power source, and a brushed motor located within the housing. The brushed motor is configured to receive power from the power source input. The brushed motor includes a first primary stator pole including a first pole neck and a first pole arc, a second primary stator pole including a second pole neck and a second pole arc, a first stator interpole including a first interpole neck, and a second stator interpole including a second interpole neck. The first stator interpole and the second stator interpole are each positioned between the first primary stator pole and the second primary stator pole.
