System designers, engineers and manufacturers in industries that employ machinery with rotating parts such as heavy machinery, wind turbines and radar may be able to avoid critical downtime that occurs from failed electrical and mechanical connectors with wireless devices.
Mechanical slip rings, through-hole slip rings and high-current slip rings
often limit designers’ and manufacturers’ ability to power systems in wet,
dirty or hostile conditions that involve vibration and 360° movement. Evaluation
kits to measure the benefits of replacing traditional electrical components and
electrical connectors with wireless slip rings and connectors were released by
"The conventional approach of using a mechanical slip ring to transfer
power and data can be problematic…. By eliminating friction-based connection
failures, wireless power transfer can reduce operation and maintenance costs,
preserve data continuity, and free designers to create innovative solutions,”
says Fady Mishriki, vice president of applications for PowerbyProxi.
PowerbyProxi’s industrial wireless power solutions provide efficient
transfer of power and data across short distances through inductive power
transfer, says the manufacturer. Proxi-Ring, a frictionless, contactless slip
ring, supplies wireless power to rotating, highly mobile industrial equipment.
It is designed for use in variable load operating environments and overcomes
the limitations of earlier generations of inductive power solutions that
suffered from excessive heat generation, says the manufacturer.
