Title: Preparation of forcer yoke
Inventor: ISHII SEIJI
IPC: H02K41/03
Filed: 1979-05-14
Abstract: PURPOSE:To simplify the process and to improve the accuracy of a forcer yoke by piling up magnetic and non-magnetic plates alternatively, and cutting the piled body by a plane perpendicular to the piling direction, before sticking the cut element to the end of the yoke body prepared separately. CONSTITUTION:Magnetic plates 4 as thick as a tooth width and non-magnetic plates 5 as thick as a groove width are alternatively piled up. The piled body 6 is cut by a plane perpendicular to the piling direction to prepare a slider tooth element 7. The element 7 is cut so tht the thickness d equals the height of a slider tooth, and the depth l fits the depth L of a forcer yoke. Then the element 7 is sticked to the end of a yoke body 8 prepared separately to prepre one pole of a forcer yoke 9. Thus, grooving is eliminated, so that the process can be simplified, and the accuracy can be improved.
