Warp field generator
From Memory Alpha, the free Star Trek reference.
The warp field generator is one component of the warp drive aboard Federation starships.
When Leah Brahms came abord the USS Enterprise-D in 2367, she critized that the magnetic plasma transfer to the warp field generators was not corresponding to the recommended specs, as Geordi La Forge had adjusted the flow. (TNG: "Galaxy's Child")
