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.
Because of the increasing ubiquity of wearable technology, it would be easy to think that design of wearable devices is routine and involves common design and engineering knowledge. Missed efforts in development will be remembered once the devices are used in the field
This grab-bag of new fasteners and adhesives work with a range of materials they can attach to, as well as a wide variety of applications. Several are for use in consumer applications, such as wearables or other compact electronic assemblies, and some of the adhesives have extended service temperature ranges and cure at room temperature.
As governments, associations, and NGOs around the world seek to protect consumers, national and regional standards are becoming mandatory, challenging manufacturers and making testing and certification necessary for any product developed and brought to market.
