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.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
