TUBULAR LINEAR MOTOR WTIH MAGNETOSTRICTIVE SENSOR

摘要

A motor (100) includes a position-sensing magnetostrictive element (98) that extends along a stator bore (110). A slider (104) slides in the stator bore (110) and includes a stack (144) of motor magnets (144). The stack (144) includes a first stack end (156) that provides a magnetic field pattern that magnetizes a region of the magnetostrictive element. The motor (100) includes shield elements such as a non-magnetic shield tube (154) and a magnetic flux diverter (162).
