Abstract
SE ENROLLA UNA BOBINA MOTRIZ FOCAL SOBRE UNA PERIFERIA EXTERIOR DE UN PORTAOBJETIVO, Y SE DISPONEN DOS BOBINAS MOTRICES DE SEGUIMIENTO SOBRE LA BOBINA MOTRIZ FOCAL. CHIPS MAGNETICOS (PIEZAS PEQUEÑAS DE MONOCRISTAL SEMICONDUCTOR QUE CONTIENE UN CIRCUITO INTEGRADO) SE INTERPONEN PREFERENTEMENTE ENTRE CADA UNA DE LAS DOS BOBINAS MOTRICES DE SEGUIMIENTO. SE SITUAN DEL PRIMER AL TERCER IMAN SOBRE LA BASE DEL ACTUADOR. EL PRIMER IMAN ESTA FRENTE A LAS SEMIPORCIONES ADYACENTES DE LAS DOS BOBINAS MOTRICES DE SEGUIMIENTO, Y LOS IMANES SEGUNDO Y TERCERO FRENTE A LA SEMIPORCION EXTERIOR DE LAS DOS BOBINAS MOTRICES DE SEGUIMIENTO. EL PORTAOBJETIVO SE SUSTENTA SOBRE LA BASE DEL ACTUADOR, USANDO RESORTES DE PLACA TRIANGULAR PARALELOS SUPERIOR E INFERIOR.
