Abstract
A linear actuator which includes a housing assembly, a shaft assembly disposed within the housing assembly, a plurality of flat magnets disposed within said housing about said shaft, and a structure to support the magnets. Because the magnets are flat magnets, the components that support the magnets may be machined with tolerances that virtually eliminate the air gap between the magnets and the support structures.
