Fiber mating surface roughness: The lower the roughness of the mating surface of the workpiece, the better. It is recommended to have a Ra value of ≤1.6.

Fiber mating surface conductivity: The mating surface (usually the circumferential surface of the rotating shaft, sometimes the end surface) must be conductive, with a surface resistance ≤10mΩ, and have a certain corrosion resistance to avoid a significant decrease in conductivity due to corrosion during the lifespan.

Workpiece hardness: There is no special hardness requirement due to the extremely low friction coefficient.

Running runout: The runout of the mating shaft surface or end surface circumference should be <0.25mm.

Installation and usage requirements: Installation method: Interference fit, bolt installation, etc.

Interference fit amount for fiber mating surface: For oil-cooled motors, the interference fit amount for the diameter should not exceed 2mm, and for water-cooled/air-cooled motors, it should not exceed 4mm.

Interference fit amount for press-fit: It is recommended to have an interference fit amount of 0.02-0.08mm. If the material is special, please contact the engineering personnel of H&C for verification.

Use of bolt fastening: Anti-slip washers and spring clips can be used for anti-loosening treatment. If thread adhesive is needed, please ensure good electrical connection between the conductive ring and the installation part after use to avoid electrical insulation caused by the thread adhesive.

Conductivity of mating surface after installation: The conductivity of the mating surface after assembly should be good: • The resistance between the aluminum ring of the conductive ring and the motor housing after installation should be ≤10mΩ. • The resistance between the rotating shaft and the nearest point of the motor housing after installation should be ≤1Ω.

Rotation direction: The motor can rotate clockwise/counterclockwise without any restriction.

Maximum speed: The maximum rotating linear speed of the shaft surface tested so far is 58.5m/s. If it needs to be used at higher speeds, please contact the engineering personnel of H&C for verification.

Operation and maintenance: Under the above normal operating conditions, the VGR conductive ring is designed to be maintenance-free for a lifespan of 300,000 kilometers in automobiles. In industrial machinery applications, the lifespan varies from 2 to 10 years depending on different applications.

Note: The above data and suggestions are based on the testing data and technical knowledge of MPT Company up to now. With more in-depth research, H&C may correct or update some of the data.
