Abstract
A linear actuator comprising a support structure; at least one magnet provided on the support structure; a carriage; at least one coil arrangement provided around the carriage; and a spring arrangement operatively connected between the support structure and the carriage to urge the carriage towards a predetermined position relative to the support structure; wherein a part of one of the support structure and the carriage is received by a part of the other of the support structure and carriage so as to constrain motion of the carriage relative to the support structure substantially along a longitudinal axis of the linear actuator.
Claims13
A linear actuator comprising
- a stationary support structure;
- at least one magnet provided on the support structure, wherein the support structure comprises two rods that are respectively secured to opposing faces of the magnet and extend in opposing directions away from the magnet;
- a carriage;
- at least one coil arrangement provided around the carriage;
- and
- a spring arrangement operatively connected between the support structure and the carriage to urge the carriage towards a predetermined position relative to the support structure;
- wherein a part of the support structure is received by a part of the carriage so as to constrain motion of the carriage relative to the support structure substantially along a longitudinal axis of the linear actuator;
- and
- wherein the support structure further comprises a tube around the carriage, wherein the motion of the carriage comprises the output of the linear actuator.
