Abstract
A solenoid actuator 1 (1A, 1B) includes: a coil 3; a first stator 10 and a second stator 20 disposed with an air gap 11 therebetween in an axial direction so as to form a magnetic path 4 around the coil 3; and a mover 50 configured to move in the axial direction toward the second stator 20 from an original position radially inward of the first stator 10 by a magnetic force generated by energizing the coil 3. The first stator 10 includes: a first yoke 14; and a first cylindrical member 30 fixed to an inner peripheral side of the first yoke 14 and forming the air gap 11.
Claims7
A solenoid actuator, comprising:
- a coil;
- a first stator and a second stator disposed with an air gap therebetween in an axial direction so as to form a magnetic path around the coil;
- and
- a mover configured to move in the axial direction toward the second stator from an original position radially inward of the first stator by a magnetic force generated by energizing the coil,
- wherein the first stator includes:
- a first yoke;
- and
- a first cylindrical member fixed to an inner peripheral side of the first yoke and forming the air gap.
A method for manufacturing a solenoid actuator, comprising:
- a step of disposing a first yoke and at least a portion of a second stator around a coil;
- a step of positioning a first cylindrical member in an axial direction with respect to a reference surface of at least the portion of the second stator;
- a step of fixing the first cylindrical member positioned in the axial direction to an inner peripheral side of the first yoke such that a first stator formed by the first yoke and the first cylindrical member forms a magnetic path around the coil together with the second stator;
- and
- a step of assembling a mover to the first stator and the second stator.
