RECIPROCABLE ELECTROMAGNETIC MOTOR Russian patent published in 2013 - IPC H02K33/10 H02K16/02 H01F7/16 

FIELD: electrical engineering.

SUBSTANCE: electromagnetic motor contains cylindrical induction coil consisting of magnetic core and excitation winding located in its circular groove; forward and reverse stroke armatures opposite to each other in coaxial relationship; return spring installed in the axial channel formed by end blind grooves in forward and reverse stroke armatures. Forward and reverse stroke armatures are made as disc and cylindrical parts interconnected rigidly. Cylindrical parts have diameters of different values. In cylindrical part of the forward stroke armature there is an internal blind groove which diameter is bigger than the diameter of cylindrical part of the reverse stroke armature, and it is capable to move along inner grove of the forward stroke armature. Disc parts of the armatures are oriented towards different poles of cylindrical induction coil. In the reverse stroke armature there is an axial bore with axial rod of the forward stroke armature located in it.

EFFECT: reduction of vibration level for electric motor housing, increase in performance and economical operation.
