Title:
MAGNETIC LINEAR ACTUATOR
Document Type and Number:
Japanese Patent JP2014181771
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To increase a tolerance limit in position alignment between a magnet of a stator and a magnetic pole of a magnet of a rotor, widen an allowable range of a spaced-apart opposing distance between the magnet of the stator and the magnet of the rotor, increase a utilization efficiency of magnetic forces of the magnets and attain its small-size, light weight and power saving.SOLUTION: A stater 1 has a structure in which a pair of magnetic poles are arranged at opposing positions while a rotating axis O1 is held therebetween (for example, a column-like permanent magnet 1A magnetized in a radial direction). A stater 2 has a structure in which a direction crossing at a right angle with a direction of the rotating axis O1 (a rotating axis direction) is defined as a direction of a moving axis O2 (a direction of a moving axis), major permanent magnets 5-1, 5-2 arranged side by side in the direction of the moving axis and a magnetic body 6-1 arranged between the major permanent magnets 5-1, 5-2. The rotor 2 is constituted such that the major permanent magnets 5-1, 5-2 are arranged with their same poles being oppositely faced to each other and a magnetic body (a permanent magnet 1A) at the stater 1 and magnetic bodies (major permanent magnets 5-1, 5-2 and the magnetic body 6-1) at the stater 2 are arranged while they are not contacted to each other.
