INDUCTOR FOR MAGNETIC-PULSE INSTALLATION AND METHOD FOR MANUFACTURE THEREOF Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: spiral coils adjoining the current leads grow in height and width. Spiral is manufactured first by cutting the coils adjoining the current leads at the pitch and width gradually increasing towards current lead ends relative to the pitch and width of coils in the central part of this spiral. Then the central coils are cut from the end of the first coil to the beginning of the last coil and a central hole is made to the base of thread ends, narrowing in the zone of the coil adjoining the end current lead. EFFECT: higher resistance of inductor to impact loads. 2 cl, 3 dwg
