INDUCTOR OF LINEAR CYLINDRICAL MOTOR Russian patent published in 1995 - IPC

FIELD: linear induction motors. SUBSTANCE: inductor of cylindrical linear motor has end shield 10 with annular conical ducts joined with frame 3 that has longitudinal slits; frame accommodates ferromagnetic parts of active layer 2. Frame is built up of three similar parts separated by longitudinal slits receiving additional insulating sheets 7 provided with rectangular bosses 8 conical at ends and located on side facing active layer; conical bosses of sheets are joined with annular conical ducts in end shields 10 and rectangular bosses 8 are placed between ferromagnetic parts 2 of active layer. End shield 10 are joined together by means of clamping members 11. EFFECT: provision for eliminating relative displacement of ferromagnetic parts 2, facilitated manufacture and reduced cost, especially as concerns long inductors; minimized labour consumption. 2 dwg
