Motor pack for automated machinery

A motor pack for an electrically driven tool said motor pack comprising:

• an electric motor,
• a lead screw extending axially through and coupled to the electric motor such that the lead screw is displaced axially by operation of the electric motor,
• a housing enclosing the electric motor and at least partially enclosing the lead screw, said housing including a front plate to which a tool head may be removably coupled, said front plate having an aperture formed therein through which said lead screw is removably coupled to a moveable element in the tool head;
• and
• tool control circuitry enclosed within the housing and electrically coupled to the electric motor to control operation of the electric motor.

A motor pack for an electrically driven tool, said motor pack comprising:

• at least one electric motor;
• a first sprocket coupled to said at least one electric motor for rotation therewith;
• a treaded lead screw;
• a second sprocket spaced apart from said first sprocket, said second sprocket having a threaded through hole engaging threads of said threaded lead screw;
• a drive belt coupling said first and second sprockets, such that rotation of said first sprocket by said at least one electric motor rotates said second sprocket and axially displaces said lead screw;
• a housing enclosing the first and second sprockets, said drive belt, said at least one electric motor, and at least partially enclosing the lead screw, said housing including a front plate to which a tool head may be removably coupled, said front plate having an aperture formed therein through which said lead screw can be coupled to a moveable element in the tool head;
• and
• tool control circuitry enclosed within the housing and electrically coupled to the at least one electric motor to control operation of the at least one electric motor.
