Motor Load-Applied Dynamometry Tester


Desktop Machine Reference             Cabinet System Machine Reference



Load-applied dynamometry of DC permanent-magnet brushed motors; test items can also include vibration, noise


Basic Functions

1. Operate motors with load to perform torque test, speed test and current test from no load to stall by step to step loading, get electrical and mechanical properties of motors, and plot dynamometry curves like U, I, Pi, T, n, Po, η;

2. Test at specific torque points;

3. Using motor terminal voltage feedback in internal precision programmable switching power supply, fully offset the test circuit voltage drop and keep the voltage actually applied on a motor accurate. Test voltage settable;

4. The motor model project test criteria can be established;

5. Set limits for test items, issue sound or light alarm in case of test data over-limit, give NG or GO result in a screen

6. Save test data, and export them via a USB interface.
