Variably adjustable cycle times
A DDA torque motor is a rotary positioning system that precisely rotates workpieces or tools in specified angular increments and cycle times. It is used wherever several work steps are to be performed sequentially on a rotating platform.
The DDA direct drive motor from IAI is a brushless torque motor without a gearbox, characterized by its high torque, inertia, and precise positioning. The ability to make flexible speed changes allows for variable cycle times. The torque motors are available for payloads up to 90 kg or 270 kg with torques of 25 Nm and 75 Nm respectively.
The rotary table is used in various areas such as semiconductor manufacturing, medical technology, the packaging industry, and other automation applications.

DDA & DDW: Technical facts
DDA and DDW torque motors from IAI are frequently used in automation technology for assembly, machining, and testing - anywhere where several work steps need to be performed sequentially on a rotating platform. They are characterized by the following features:
- Direct drive without gearbox: The rotary indexing table transmits the torque directly without mechanical transmission. This results in high dynamics, precise positioning, and low maintenance.
- Variably adjustable cycle times: The speed can be easily changed so that the cycle times can be set precisely.
- Compact design: Despite their high performance, both rotary indexing tables are compact in design, which generally saves space and is advantageous in confined conditions.
- High repeat accuracy: The DDA rotary indexing table offers high repeat accuracy of ±0.0055° (±19.8s) with 17-bit resolution and ±0.00103° (±3.7s) with 20-bit resolution.
