How to specify a slip ring
Specifying the right slip ring requires understanding its role within a larger mechanism and the environment it operates in. To ensure the design meets its intended application, consider the following key criteria:
Primary design criteria
Physical dimensions:
Include attachment arrangements and de-rotating features.
Circuit requirements:
Detail the number of circuits, maximum current, and voltage.
Operating environment:
Account for factors like temperature, humidity, salt fog, shock, and vibration.
Detailed specifications
Electrical resistance:
Maximum resistance between rotor and stator, typically measured in milli-ohms.
Circuit isolation:
Isolation between circuits, expressed in dB.
EMI protection:
Isolation from external electromagnetic interference (EMI), also expressed in dB.
Torque requirements:
Starting and running torque specifications.
Weight:
Define weight limitations for the assembly.
Data circuit descriptions:
Include specific data requirements.
Optional features
- Connectors
- Resolvers
- Encoders
- Fluid rotary unions
- Coax rotary unions
- Fiber optic rotary joints
