We see from your search that you're looking for information on the term "Dynamic Braking",
and we have a large number of manufacturers' news releases and technical articles here on Engineeringtalk which will be of interest.
Let me be your guide.
Start with
the news release Drives suit compressed air systems from
Lenze, which we summarised at the time by saying "The IceTech range of blasting equipment employs a high-pressure pump powered by a single three-phase 230V 50Hz motor to propel the dry ice pellets into a compressed air stream".
A few weeks before,
we featured the news release Heaters keep switchgear free from moisture from
Pentagon Electrical Products: "3500 anticondensation heaters will be used in switchgear panels in the world's tallest building".
In August 2007, we covered the news from Parker Hannifin - SSD
concerning its 890PX AC drive system
- take a look at AC drive system cuts installation time
which says: "Tthe 890PX' dedicated plug-in drive modules make setup or subsequent reconfiguration quick and simple, and standard pre-engineered hardware cuts costs still further".
Take a look also at the news release from Lenze-ACTech, Drive survives freezing temperatures,
as well as Wire feeders are rugged but lightweight from ESAB,
and Drive unit suits road roller wheels from Bonfiglioli UK Mobile Solutions.
