Safety is an important factor when deciding on the best
brake for your application.
The Ogura RNB brake is primarily
used for holding a load in place. When the
servomotor is running, the brake field is
energized, so a magnetic field is generated,
attracting the steel pressure plate. When
the pressure plate is pulled toward the
field, it compresses six small coil springs.

The article also explained how smaller high efficient air pumps are being used in fuel cell applications to help push air and hydrogen through the fuel cells proton exchange membrane creating electricity.
On July 9th, Machine Design published an article written by Ogura on considerations that design engineers should follow when designing in electromagnetic clutches and brakes. The original article that was submitted is attached as well as the link to the article in Machine Design.
There is a typo in the low speed formula. The reflected inertia of LG1 is currently listed as JLG1/(NS2/NL1)2. The correct formula should be JLG1/(NL1/NS2)2. In the high speed operation the reflected inertia of large gear 2 and small gear 1 is repeated twice. JLG2 + (JLG1/(NL1/NS2)2) should be eliminated from the first half of the equation.
These mistakes were caught by Neal Middleberg, who is the Chief Engineer of Bowe Bell and Howell, who uses this type of formula to help define total system inertia in complex machines.
In the December 11th issue of Machine Design an article, In the Reporters Notebook section, talked about how the Ogura Spring Applied Brakes help the Action-Cam Company control their high definition stadium camera. The link above shows the article as it appeared in the Ogura Newsletter. If you would like to see the Machine Design article please visit www.machinedesign.com.

Ogura Industrial provides TimberKing with a clutch/brake that enables a rotating band saw to be started and stopped remotely. Now an operator can remain behind the mill and control all functions. Upon cutting power to the clutch/brake, the brake slows to meet pre-set stop time requirements. Remote control over blade engagement and disengagement also minimizes the stress on the blade band.
Ogura Industrial was featured in an industry trade magazine showing how a small horsepower diesel engine and a number of Ogura clutches can run the various generators and compressors required on a tractor trailer. The advantage with running the smaller horsepower engines is that the drives do not have to run their large diesel engines all night long just to provide heat and electricity. A full version of the article as it appeared in the Ogura newsletter is attached to the link.
With the increase in usage of electric PTO clutch/brakes in the outdoor power equipment industry, many customers are doing their own trouble shooting of PTO clutch/brakes.
