I found a patent describing an actuator with a “forcer rod (30)”. Is this arrangement identical to your subject?
57) An example actuator assembly includes an actuator (32) configured to move a
rod (30).
:
A linear variable differential transformer (LVDT) is a type of VDT that can be used for measuring linear displacement of a LVDT core …. An LVDT core can be coupled to a forcer rod of a linear actuator to measure movement of the forcer rod.
[0008] Figure 1 is a schematic view of a plurality of LVDTs 10A-B that are redundantly configured to measure a linear displacement of a
forcer rod 30 of a linear actuator 32. …
0009] A plurality of
magnets 34surround the forcer rod 30 along a length of the rod between a first magnet 34A and a last magnet 34N. The linear actuator 32 includes a plurality of stators 36A-C. The forcer rod 30 is movable along the central longitudinal axis A by applying a voltage to one or more of the
stators 36. I
