<P>PROBLEM TO BE SOLVED: To provide a linear actuator reduced in size by providing a triple redundancy linear position sensor in the hollow rod of a rotor by forming a motor in a triple redundancy type. <P>SOLUTION: The triple redundancy type linear actuator includes the hollow rod (21) linearly movably in the cylindrical threaded element (10) of the cylindrical rotor (11) of the triple redundancy type stator (3), and a triple redundancy type linear position sensor (30) provided in this hollow rod (21), thereby constituting the small-sized triple redundancy type. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
