| Abstract |
For the movement of robot arms electric drives employing permanent magnet synchronous motors are increasingly used, because they offer a lot of advantages due to the DC-Motors. At present the power conditioning is performed in a converter cabinet near the robot while the drive motors are located in the robot arm. The necessary wiring is inconvenient in some respects. In our concept the wiring is completly replaced with a middle frequency power bus without any movable parts. Rotatable transformers in the robot joints transfer the energy without any restriction to the motion of the arm. Decentralized power converters transfer the fixed voltage fixed frequency of the bus into variable voltage variable frequency for the drive motors. Experimental results obtained from a test setup of some ten kilowatts are presented. |
