20100133924 | COMPACT LINEAR ACTUATOR AND METHOD OF MAKING SAME - Disclosed herein are methods and apparatus for a guided single-phase or multi-phase linear motor actuator with a snap-together design. Some embodiments include the ability to monitor and/or adjust work being done, yet with a cost that is comparable to that of cams or pneumatic devices. In one embodiment, a coil is attached to a bobbin assembly that is secured behind a piston. To prevent rotation of the piston during operation, a spline bearing may be slidably fitted onto one or more grooves of a spline shaft disposed within the piston assembly. One or more cylindrical magnets surrounding the coil actuate the piston based upon the direction that current is traveling through the coil. Since the electromotive force generated is linear with respect to the spline shaft, unwanted lateral force acting upon the spline shaft can be reduced and/or eliminated. | 06-03-2010 |
