Winding ohmmeters RMO-M series measure winding resistance of inductive test objects such as electrical motors and generators. Motor test or generator test of winding resistance is especially important for early-stage failure detection.RMO-M series instruments generate true DC ripple-free current with automatically regulated measurement and discharge process. Even more, test instruments are portable and enclosed in a metal casing.Applications supported by DV Power motor/generator test equipment include:Winding resistance measurement of generators and electrical motorsResistance measurement of high-current bus bar jointsResistance measurement of cable splicesAll of the above-mentioned measurements are performed with the highest accuracy. The advanced DV-Win PC software enables collecting both numerical and graphical results. These features provide an easier and more efficient analysis. After the test, a DV-Win software generates a test report a single click. Finally, a user can easily customize the report and save it in different formats, such as XLS and PDF.

MR 270 C-A -
Schuetz Messtechnik GmbH
The MR270C-A is specially designed for electric resistance measurements in cable industry applications and inductive loads (transformers, motors). It is perfectly fit both for measuring the meter resistance in connection with a corresponding resistance measurement holding device or for final acceptance control of power cable reels. In the case of cable reels, which often have a cable length of several kilometers, both the compensation of the inductive component and the ability to perform measurements in the presence of high noise levels are important. This also applies to the winding resistance of transformers and motors.

Motor Starting Resistors are used to reduce the voltage at the motor terminals and also decrease the starting current. Motor Starting Resistors are necessary because the self resistance of a motor armature is very low. When the voltage is first applied, excessive current will flow. For limiting this current, since there will be no resisting back electromotive force (emf),some series resistance can be added to the armature windings.
