Load-Free Dynamometry Tester





DC permanent-magnet brushed motor (without reducer) load-free dynamometry, and also electric strength, current ripple analysis, vibration, noise, label print & check, data upload to server, and all other FAT and management items; Motors of special specifications can be tested upon order request.


Basic Functions

1. Perform no-load motor test to obtain the electromechanical properties of a motor, just power the motor to perform no-load test; it eliminates the operation of brakes, torque sensors, couplings and countershafts, and makes the test convenient and fast

2. Display of torque, speed, input power, output power, voltage, current, efficiency and other dynamometry curves, or display of data at POLs (points of load), stall points and other designated 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.
