INFRARED MEASURING FOR THERMOGRAPHIC ANALYSIS IN MAINTENANCE, SERVICING AND REPAIRDuring normal operation electrical components and mechanical bearing parts are warming up but are protected against overheating by constructive measures. In case of failure typical local hotspots occur which may lead to consequential damages but these can simply be identified by thermal analysis. [ [more] ]


Revision of all drives within the high-voltage, low-voltage and DC range.

In the course of such overhauling and reconditioning the following can be carried out:

  • Diagnosis of mechanical and electrical fitness for operation
  • Steam jet cleaning and drying of winding components
  • Sand blasting of motor components
  • Fitness check for sensors and monitoring devices
  • Dynamic balancing  of the motors
  • Maintenance for sleeve bearing, seals and gaskets
  • Exchange of rolling bearings

Exterior protective coating according to Helmke standard as well as customer requirements:

  • Sand blasting of complete machine or its elements
  • Painting of all machine parts on open circuit air-cooled machines
  • Special coating according to customer requirements for offshore applications
  • Test reports for painting layers it`s adhesion and coat thinkness

Documented final check testing

  • Final assembly and testing of motors with test report
  • Partial Discharge Measurements of the windings
  • Tan Delta measurement for the windings
  • Polarization measurement for the windings
  • Load test with heat-run at rated load
  • Specific tests subject to customer specification
