MATERIALS: The small spring applied brake series from Ogura (models MCNB 2, 5, and 10) have been redesigned and will now have a thinner profile. The brakes overall reduction in thickness is around 30 percent. Advances in friction material have allowed the brakes to maintain their same torque rating while eliminating the need for higher force springs and a correspondently higher wattage coil. The new thinner spring applied holding brakes are ideal for the servo motor and robotics industries where size and weight is always a concern. Since less steel is used in the coil shell and less copper in the windings, cost of the brakes are also lower than the current MCNB series. On some of the models, the outside diameter has been slightly reduced but all of the models have the same through whole mounting dimensions as the current MCNB brakes, so brake models will be interchangeable.
Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
