Association With Grounding Devices TRIZ Cases
- Conductive Nonwoven Grounding Ring for Low-Resistance E-Mobility
Embedded conductive particles cut nonwoven grounding-ring resistance to ≤10Ω while preserving flexibility and low friction in dynamic e-mobility use.
- Bearing Ring Conductive Layer for Stable Motor Grounding
A conductive layer on the bearing rotating ring keeps grounding brush resistance low, limiting discharge damage and vibration over time.
- Rotating Electric Machine Housing Layout for Lightning Current Bypass
Spaced retaining members route lightning-induced current around the housing, protecting electrical components and preserving system stability.
- Rotary Shaft Grounding Structure for Abrasion Powder Containment
A case-wall recess traps conductive abrasion powder from shaft grounding contact, protecting bearings and keeping the drive unit compact.
- Capacitive Discharge Shield for EV Motor Bearing Voltage
A grounded capacitive shield diverts common mode voltage from EV motor bearings, reducing EDM damage and avoiding costly ceramic bearings.
- Motor Shaft Ground Ring Structure Using Inner Shaft Contact
By inserting the ground ring contact into the shaft bore, this case grounds axial rotor current with fewer parts, lower cost, and no longer shaft.
- Conductive Seal Ring Structure for Lubricated Rotary Shafts
An annular conductive seal member with radial gaps preserves shaft conductivity under lubrication while saving space and dissipating noise.
- Rotor Grounding Assembly With Axial Contact to Reduce Wear
An axial conductive link grounds the rotor through the casing, cutting arc-related bearing wear, friction, and shaft-side contact damage.
- Motor Rotor Position Sensor Ground Layout Against EMI and ESD
Separate ground patterns for Hall and encoder magnetic elements cut EMI and ESD risk in compact motor rotor position sensors.
