ELECTRICALLY DRIVEN TOOL Russian patent published in 2009 - IPC B25C1/06 

FIELD: mechanical engineering and metal working.

SUBSTANCE: invention relates to electrically driven tool, its drive comprising movable shuttle (10) connected to striker (13) and drive motor incorporating at least two, assemblies (8, 9) of electromagnetic frames interacting with aforesaid shuttle. The latter is arranged to move along frames (8, 9). Note that each aforesaid frame incorporates electric coils (15) to induce magnetic field across shuttle (10) and control unit to control current in coils (15) which generates required force to move shuttle (15). Frame assemblies (8, 9) induce magnetic field, directed, in fact, across shuttle motion.

EFFECT: reduced sizes, economic current consumption from battery.
