20090166157 | Roller Drive and Roller Transportation Device - There is described a roller drive and a roller transport device equipped with the roller drive. The roller drive comprises an electric machine and ends, wherein at least one end has a heat-conducting end contact face. The contact face is intended for coming into heat-conducting contact with a side cheek of the roller transport device. This allows the cooling to be improved. Furthermore, the roller drive can also be designed in such a way that it has a device for accommodating electrical components, wherein the device is intended as a torque support for the electric machine. A regulating device and/or a communication device can also be integrated into the device. | 07-02-2009 |
20100121467 | CONTROL ARRANGEMENT WITH CORRECTION MEANS FOR SYSTEMATIC POSITION-DEPENDENT ERRORS - A control arrangement for an electric drive with a control which processes desired values and actual values of the electric drive in relation to a desired-actual control is provided. A determination device determines a derived variable in an iterative manner in accordance with the actual values and the derived variable is fed to an evaluation device. The evaluation device associates the derived variables with position values of the drive and determines, after accumulating several derived variables, characteristic values of a systematic error in the desired values and/or the actual values. In accordance with the determined characteristic values, the evaluation device determines correction values and switches the correction values to the desired values, the actual values or the difference of desired and actual values. | 05-13-2010 |
