Filtering Increases Motor Bearing Life - Addition of KLC Significantly Reduces Common Mode Current

  • A technical overview of the application of a KLC dV/dTGuard to increase motor bearing life and overall system up-time by reducing common mode motor bearing current.

Supplemental Information regarding TCI HarmonicGuardTM filters

  • A concise and complete text regarding the use of HarmonicGuard(tm) Drive- applied filters, including performance, application guidelines, features and benefits.
Eliminating motor failures due to IGBT-based drives and long leads
  • New IGBT based drives offer great benefits including reduced noise, smaller size, higher performance. This paper discusses the use of IGBT based drives in applications requiring long wire-lead distances.
Meeting IEEE-519 harmonic limits (ZIP format - includes eps graphics) 
(and now available in pdf form - click here)
  • More than 25,000 copies of this paper are in print. It has been called the premier resource for understanding IEEE-519-1992, and for applying drives while considering the harmonic limits set forth by the recommendation.

KMP Support: 

A new (10/13/98) tool is available to demonstrate the performance of KMP (or other 12-pulse transformer technologies). Download kmprslts.xls. It includes:

  • KMP - outline/comments.
  • Harmonics - demonstration of how the harmonic cancellation calculation can be used to predict the harmonic pair to be canceled given the pulse number. Also, a table and resultant graphical representation of a given harmonic on a terminal pair. Can be used to note the sensitivity of a 12 pulse transformer (any) to phase angle and secondary + to - voltage ratio error also, impedance imbalance.
  • Converters - A table and resultant graphical comparison of the ripple on the DC rails from a 6 pulse and 12 pulse converter.
  • Phase Shift - A table illustrating the limitations of phase angle accuracy and primary to secondary voltage ratio accuracy. Only integer turns can be used, thus 15.000 degrees is not possible.

Representative Wave forms:

The wave forms included in this self-extracting file are before and after shots of: 

      • DC drive input voltages
      • AC drive input currents
      • AC drive bus voltages on trip
      • motor terminal voltages with long-leads
      • short circuit currents on motor failure

These may be useful in a presentation or for diagnosis of a specific problem. This is a self-extracting executable file. The enclosed files are .gif format.
