ELECTRIC POWER TOOL

摘要

An electric torque delivering impulse tool comprising: a housing (10) with a front end (10a) and a back end (10b), an electric torque delivering motor (12) with a rotor (14) that is arranged to rotate with respect to a stator (13), an output shaft (16) arranged at the front end (10a) of the housing (10), and a pulse unit (15) intermittently coupling said motor (12) to said output shaft (16), wherein the pulse unit (15) comprises an inertia drive member (18) that is connected to said motor rotor (14). The rotor (14) and the inertia drive member (18) are rigidly assembled to each other without play so as to form one integrated rotatable structure which is mounted as one single unit inside said housing (10).
