DS720 Motor Armature Tester (universal type)

Appearance Reference                      Application Case

Scope

Applicable to electrical properties test of motor armature with any number of commutator bars, for example, automotive motors, motorcycle starter motors, power tools motors, traction motors, vacuum cleaner motors, fitness equipment motors, motors for kitchens, permanent magnetic micro-motors, special-purpose motors

Functional Features

● Measure the welding resistance accurately to the micro-ohm level; the automatic judgment threshold for armature welding resistance can be set to 100 micro-ohms (ie 0.100 milliohms) or even smaller; discover armature rosin joints and nonconforming welds fast and accurately; the screen provides fault location information to facilitate armature troubleshooting

● Resistance test between any bars; automatically identify bar to bar short circuit, broken wire, resistance over-limit, and provide fault information

● Proprietary bar-to-bar resistance fuzzy sort and identification; automatically identify single-fork, double-fork or large and small bar winding process, and hookup direction; automatically track and test an armature regardless of where it is placed; analyze the number of turns, diameter of enameled wires and slight difference in winding tension by this means

● Automatic alarm upon wrong coil CW/CCW hookup direction

● Unique automatic range switching and test tracking; therefore a higher accuracy than other similar instruments throughout the measurement range. It is not required to set the instrument measurement range as the armature resistance range is not required to know beforehand; even an ordinary operators can sample an armature with its parameters unknown very easily and formulate the automatic judgment criteria

● Automatic, multiple-wave judgment of turn-to-turn surge test between any bars under any form of surge, any times of surge;

● HIPOT, turn to turn surge test voltage settable, automatically generated and regulated; test data immune to fluctuations from external grid; offset the inherent leakage current of test system automatically

● Automatic ambient temperature compensation and high voltage test leak compensation to ensure test accuracy

● Automatically count the number and pass ratio of test samples, make statistics of nonconformities

● Automatically/manually analyze, and store the automatic judgment criteria of armatures of different models and specifications

● Double-station configuration, high test efficiency
