'APPARATUS ON A SPINNING ROOM MACHINE, ESPECIALLY A SPINNING PREPARATION MACHINE, FOR EXAMPLE A FLAT CARD, ROLLER CARD OR THE LIKE, FOR MONITORING AN ELECTRIC DRIVE MOTOR.',

摘要

pAn apparatus on a spinning room machine, especially a spinning preparation machine, is arranged for monitoring the load on an electric drive motor 22, which is connected to an electronic speed-setting and/or regulating device, a rotating operating element 4 being connected to the drive motor. In order to monitor the drive motor so that no damage occurs under different operating conditions, there is a device 47 for automatically determining the loading of the drive motor during operation, which is connected to a device 48 for comparison with pre-set values for the loading, to which there is connected a display and/or switching device 45, 49 which can be supplied with electrical signals in the event of departures. The loading can be determined from the power consumption, torque, effective output, phase shift, reduction in speed of the roller or slip of a belt drive./p[GB2438497A]
