The AEGIS SGR Bearing Protection Ring protects the bearings of VFD-driven motors from electrical damage, and the new AEGIS Universal Mounting Kit (U-Kit) simplifies its mounting on most ac motor shafts. Electro Static Technology's kit includes the AEGIS grounding ring and mounting hardware for most motor designs. Ordered based on the NEMA "u" shaft diameter, the kit contains the correct size ring for the motor and four styles of brackets with bolts and lock washers that can be used in various configurations, depending on the contours of the motor's end bracket.
Useful for HVAC service contractors, motor repair shops, plant maintenance departments and original equipment manufacturers, the ring prevents electrical "fluting" damage in the bearing, bearing noise, costly motor repairs/replacements and downtime by safely channeling VFD-induced bearing currents to ground. To simplify the installation of the ring on NEMA frame motors, the brackets in the U-Kit may be mounted on the motor either by drilling and tapping small holes or using AEGIS Conductive Epoxy.
The ring's conductive microfibers are embedded securely in the AEGIS FiberLock channel and completely surround the motor shaft, providing millions of discharge points for harmful shaft currents. This design creates the path of least resistance that effectively diverts these currents away from bearings to ground. The microfibers themselves are engineered for flexibility to prevent breakage. The AEGIS ring is maintenance-free and lasts for the life of the motor.
Are they robots or androids? We're not exactly sure. Each talking, gesturing Geminoid looks exactly like a real individual, starting with their creator, professor Hiroshi Ishiguro of Osaka University in Japan.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
