All electric motor engineer globally expects a “superconductivity” material to bring bearing currents to grounding WITHOUT time delay, hope it will avoid the bearing failure since the bearing currents, but it’s just a “hope”.  However, Vookey’s solution of Fully Adjustable Grounding Ring (FAGR) product can shorten the current conduction time within 0.1 seconds as much as possible.

Patent Vookey Solution:

With Vookey FAGR products bring a more higher performance and very low cost solution compared with triditional grounding brush:

◆  Dragging torque in average 0.07Nm

◆  Resistivity lower than 100 mΩ stably

◆  Shaft no obvious damage

◆  FAGR no obvious wear loss 

◆  FAGR no clamping force loss

Integrated FAGR with Vookey Oil-sealing solution:
