Brakes for high-speed SCARA robots and more

Precise positioning of semi-conductor wafers during SCARA assembly operations requires instantaneous braking and holding power while minimizing heat in the system. The latest compact and slender Miki Pulley BXR-LE brake models provide the needed, perfectly controlled braking in a confined area of the system using minimal power. The braking response and holding power of this power-off engaged brake makes it ideal for this and other high-speed applications. The BXR-LE brake uses 24 VDC for a split second to overcome compression spring inertia to open the brake, then consumes only 7 VDC by utilizing the BEM power control module.

Honda's E-Clutch for motorcycles turns manual bike into automatic -- or not

Honda Motor Co. has released new details about its E-Clutch technology for motorcycles, which it claims is "the world's first automatic clutch control system for a multi-gear manual motorcycle transmission, enabling smooth starting, shifting gears, and stopping without the need for the rider to operate the clutch lever."

E-Clutch could come as an add-on to a new Honda motorcycle or -- maybe sometime in the future -- as an aftermarket add-on system to any bike. It uses electronic control tech to provide instantaneous, fine-tuned clutch control for optimum performance in situations where the driving force changes, such as starting, shifting gears, and stopping, to achieve smooth starting, shifting gears, and stopping more natural than a rider's manual clutch operation.

One of the main benefits of the technology is that it is user-engageable, meaning riders can turn it on or off whenever they see fit. Love riding your bike in the country or on the highway and the feel and control of manual shift for longer trips? Turn E-Clutch off.

"Entrusting clutch operation to the Honda E-Clutch system on winding roads allows the rider to concentrate on throttle, brake, and gear-shifting operations, and on controlling motorcycle behavior," says Honda on its website. "And in circuit racing and other sports riding scenarios, in addition to conventional quick-shifter control, the system can also instantly half-clutch to provide control appropriate to the motorcycle state, which can be better than a quick shifter in reducing changes in motorcycle behavior due to gear shifting."

Having the system on when riding in town or a city could be a real plus. Honda says the clutch can be operated "like a normal manual motorcycle gripping the clutch lever, even when the clutch is controlled electronically," allowing the system "to be used by more riders of diverse riding experience and skills, who can concentrate on the fun of riding in more comfort."

Honda says the lightweight and compact system can be installed "without major changes to existing engine layouts." Honda plans to incorporate the E-Clutch into its FUN motorcycle models "over time." The system also looks like it would work as an aftermarket product, but there is no indication right now Honda will offer this.

According to Cycle World, "The E-Clutch uses two electric motors geared together onto a set of reduction gears, all mounted in a pod attached to the clutch cover. ... The reduction gears are connected to sector gears that, in turn, act on the same clutch release shaft that the conventional, bar-mounted clutch lever is connected to (by a cable, in the case of the CB650R). The final sector gear acts on the release shaft via a cam that allows the manual clutch lever on the bar to override the electronic system. So when the electronics are turned off, the clutch operates as a conventional unit."

There is an angle sensor in there, too. Designfax highlights these types of sensors, like those from Novotechnik, a few times a year. Honda has a diagram of the setup on the E-Clutch info page.
