Abstract
An electric actuator includes a stationary support and a guide system having a single stationary guide joined to the stationary support having an axis. The actuator also includes a stationary assembly secured to the stationary support. A moving assembly is movable relative to the stationary support on the guide, where the moving assembly and the stationary assembly provide at least two sets of interacting magnetic fields disposed about the guide at equal angular intervals. A test specimen support is joined to the moving assembly and disposed on one side of the stationary support so as to move along the axis with movement of the moving assembly, the axis extending through the test specimen support.
