MAGNETIC CIRCUIT MANUFACTURING PROCESS Russian patent published in 1995 - IPC

FIELD: electrical engineering. SUBSTANCE: magnetic circuit core is made by multilayer winding of strip material whereupon toothed region of core is manufactured. Its members are built up of L- and U-shaped laminations having different length. U-shaped laminations are first to be arranged along member on its edges and L-shaped laminations alternating with U-shaped ones are fitted inbetween. Several L-shaped laminations are installed along member to form toothed region with trapezoidal shape of its end surface. For final procedure, all laminations are glued together and baked. EFFECT: reduced labour consumption in manufacturing magnetic circuits of butt-end electrical machines; simplified procedure dispensing with special process equipment. 6 dwg
