FIELD: electrical engineering; off-line low-power device. SUBSTANCE: motor has set of magnetic poles with wound armature rotating in-between. Connected in parallel with its winding turns is hydraulic member disposed on armature whose electrode polarity depends on armature position and reverses when armature turns through 180 deg. EFFECT: provision for using ac hydraulic member to replace commutator and brush gear. 1 cl, 1 dwg |
