Motor Testing Solution
Motor Stator Testing System (Micro-ohm meter)

The 6913 motor stator test system collocates the MT-6913 and the 7605 tester. Optional 6365 benchtop LCR Meter for testing inductor. It is provided with eight 4-line independent measurement test points and 13 channels. The testing projects include the DC resistance tests which may detect the errors of copper wires that is over-tight during winding, broken or connecting. Besides, the Hipot testing on the required safety regulations, and the client respect project of the Impulse/Surge are included as well. With the most advanced Impulse/Surge tester takes waveform comparison to avoid the Corona Phenomenon that is caused by possible damage. It provides a complete solution of standard test project to the international manufacturers and serves as a further checker for your products. The motor stator test systems that match up the programmable interface and the simple operation can be quickly imported into the production lines and the quality control center. 
Standard system is the Super Space-Saving Desktops Tester.
Optional system is the Systematic Modular Cabinet Tester.

  • Both the internal wire resistance and the contact resistance will not affect the measurement. Using the 4-wire measurement will be more accurate than others
  • To meet the standard test projects requirement of the international companies
  • To control and analysis the programs will reduce the human careless and misjudgment
  • Easy to edit environment and easy to learn
  • It can test multiple sets of DUTs simultaneously(depending on the number of winding set of the product)
  • When there are several DUTs are tested, it could identify the undesirable sets individually
  • The Impulse/Surge with waveform comparison is a non-destructive analysis
  • Maximum saved files will be up to 100 sets
  • It provides the password function
  • Speeding test could save time and improve efficiency
  • Chinese/English screen could be switched arbitrarily
