ELECTRO-MECHANICAL CONVERTER FOR IMPACT MACHINES Russian patent published in 2012 - IPC H02K33/00 H02K41/25 H02K41/35 E21C37/00 

FIELD: electricity.

SUBSTANCE: electro-mechanical converter includes asynchronous linear cylindrical engine (ALCE) of alternating current in the stator housing 1 of which there located are stator coils 2. The housing 1 is connected to the housing 11 of linear cylindrical engine (LCE) of direct current. The armatures of the said engines are united with the possibility of adjusting the acceleration of the formed common armature and its reciprocating movement within the limits coaxially the stator 2 coils in slider bearings 5 of ALCE, slider bearings 10, 71 of LCE. Common armature is equipped with stabilisation means preventing its turning about axis. LCE is performed in a form of accelerator and serves for providing a necessary speed to the common armature in the end of working stroke.

EFFECT: increase of specific energy of impact and working stroke of common armature, provision of possibility to control speed, acceleration, shift and energy of its movement, extension of application field by means of provision of maximum working stroke length of executive impact element not less than 400 mm.
