Gravitor
Design a gravitor by picking one part from each role, then commit it as a planned build. Browse available parts below.
Gravitor builder
Pick one part of each role plus a target voltage. The calculator compares the applied voltage to the dielectric's breakdown ceiling, applies your safety margin, and tells you whether the combo is acceptable. Once it's green you can commit it as a planned build on the Equipment page.
% of the dielectric's rated breakdown allowed before we flag it. 50% = conservative, 95% = right at the edge of material failure.
Recommendations
- →Pick a dielectric so we can validate the breakdown field.
- →Select an emitter.
- →Select a ground plate.
A new Gravitor is created with status planned and the three sub-parts attached. Move it through the build pipeline on the Equipment page.
Emitters
20Positive electrode — creates the electrostatic field.
