We see from your search that you're looking for information on the term "Direct Drive Motors",
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 Direct-drive motors come in smaller sizes from
Danaher Motion, which we summarised at the time by saying "With virtually no limitation in terms of the motor to load inertia torque ratio there is no need for mechanical gearing systems between the motor and load".
Several months prior to that,
we featured the news release Servomotors improve energy efficiency from
Motor Technology: "Direct drive motors are fitted directly to the load, dispensing with the need for additional components such as gearboxes, couplings, belts, chains and sprockets".
In October 2006, we covered the news from Lambda Photometrics
concerning its M-230, M-238 and M-235
- take a look at Motorised actuators keep equipment on the level
which says: "High load motorised linear actuators meet the increasing need for precision levelling and alignment in industrial machinery".
Take a look also at the news release from EMS, Low-profile motors fit every application,
as well as Miniature motors suit all applications from EMS,
and High torque to size ratio for direct drive motors from Micromech.
