6 MW HELMKE FULL LOAD TEST FIELDTo meet customers requirements and HELMKE's aspiration to work always with state of the art technologies, the HELMKE Group has invested in a new testing field on its location in Pulversheim, France. The testing field is also available for final customer inspections and external testing orders.
HELMKE 24/7 DELIVERY PROGRAM 5 MW SOFTSTARTER AVAILABLE FROM STOCKThe HELMKE group, with a heritage of motor and generator sales/stock keeping/production going back more than 90 years, is continuously investing in its production facilities and its extensive stock.
One of our standing customers in Scandinavia had to experience a great winding damage of the drive motor mentioned above. As consequence of that failure each day several thousand tons of cement could not be produced.
After thorough examinations of the motor it was obvious that the repair works would take quite a few months. Because of comprehensive investigations J. Helmke & Co, Hannover succeeded on the market to purchase a machine of identical construction with high wear which we could repair for quick operation.
For example, we carefully cleaned the winding elements to examine the quality. The evaluation of the quality was done on the basis of tan-D, partial discharge and polarization index measurements.
The mechanical components were thoroughly examined, too and among other things the shaft assembly was examined by means of ultrasonic test and magnetic crack detection. In addition to that, we had to determine extensive damages on the machine housing and we had to examine the possibility to copy several missing housing parts.
After a 4 weeks handling time for comprehensive reconditioning works of the motor components and final successful inspection and testing the motor left our repair workshop to be assembled in the cement factory.
