MAGNETOSENSITIVE PICKUP FOR CONTACTLESS ELECTRIC MOTOR Russian patent published in 1995 - IPC

FIELD: semiconductor pickups. SUBSTANCE: magnetosensitive pickup has semiconductor Hall plate 1, polymide base 2 of flexible printed circuit board, printed conductors 3 of printed circuit board, case 4 of pickup, mica backing 5, compound 6. Hall plate is rectangular silicon plate with controlling (current) and Hall electrodes being formed on one of its planes. Decrease of active region of Hall plate enabled magnetic sensitivity and operational stability of pickup to be raised. EFFECT: raised magnetic sensitivity and operational stability with decrease of active region of Hall plate. 2 dwg
