Abstract
A motor pack for an electrically driven tool includes at least one electric motor and a linearly displaceable member coupled to the electric motor such that the linearly displaceable member is displaced axially by operation of the at least one electric motor. The motor pack further includes a housing enclosing the electric motor and at least partially enclosing the linearly displaceable member. The housing includes a front plate to which a tool head may be removably coupled. The front plate has an aperture formed therein through which the linearly displaceable element can be coupled to a moveable element in the tool head. The motor pack also includes tool control circuitry enclosed within the housing and electrically coupled to the electric motor to control operation thereof.
