| Number | Title | Issue Date |
| 8159174 | Method for adapting controller parameters of a drive to different operating states A method is provided for adapting controller parameters of a drive to different operating states. A control loop includes a PID controller whose I gain factor is adapted to a drive velocity and/or whose D gain factor is adapted to a drive current, and consequently t... | 04/17/2012 |
| 8040099 | Position device in gantry type of construction In a positioning device in gantry type of construction, due to a special arrangement of the position-measuring devices used for the positioning, errors due to thermal expansion of the positioning device may be avoided to a great extent. In particular, attention is g... | 10/18/2011 |
| 7723892 | Synchronous motor having multiple coil segments A synchronous motor includes multiple coil segments, each of which has an iron core in the form of a core stack that is wound with a coil. The coil segments are characterized in that the coils press fastening elements having at least two legs against two opposite su... | 05/25/2010 |
| 7719144 | Vertical actuator having a gravity compensation device A vertical actuator has a stationary part that includes an upper part made of magnetic material which is magnetically separated from a yoke which bears a coil.
