These magnetic particle brakes have a hollow shaft, and don't need a precision alignment shaft for installation. They slide on and couple with a roll pin or integral clamp, a torque arm holding the brake's body still. They are used where variable, smooth slip torque is needed, such as in winding systems. Input current controls the unwind tension. Torque comes from magnetizing microscopic stainless steel spheres. A higher electric input makes for a stronger internal magnetic field, which creates higher torque that is independent of slip RPM. Hollow shaft brakes from 0-15 to 220 lb-inches. Larger solid shaft brakes, as well as clutches up to 300 lb-feet with 1,900W heat dissipation are available from stock.
Last year at Hannover Fair, lots of people were talking about Industry 4.0. This is a concept that seems to have a different name in every region. I’ve been referring to it as the Industrial Internet of Things (IIoT), not to be confused with the plain old Internet of Things (IoT). Others refer to it as the Connected Industry, the smart factory concept, M2M, data extraction, and so on.
Some of the biggest self-assembled building blocks and structures made from engineered DNA have been developed by researchers at Harvard's Wyss Institute. The largest, a hexagonal prism, is one-tenth the size of an average bacterium.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
