AC Dynamometer / electric dynamometer / electronic dynamometer

Main functions:

1. The measurement of the DC resistance of the winding in the actual cooling state

2. No-load characteristic test: the determination of no-load current and no-load loss, Determination of iron loss, mechanical loss, etc., no-load characteristic curve drawing

3. Locked-rotor characteristic test: measurement of locked-rotor current, locked-rotor torque and power, locked-rotor characteristic curve drawing

4. Load test: under rated voltage and frequency, Stator winding loss, rotor winding loss and load stray loss (direct/indirect method), total loss and output power determination, load characteristic curve drawing.

5. Determination of efficiency: efficiency test method, five kinds of A, B, C, E, F

6. Heating test (resistance temperature rise/temperature test )

7. Maximum torque measurement: MS curve can be detected

8. Minimum torque measurement:Can detect MS curve

9, centrifugal switch disconnection speed determination

10, other tests: over-speed test
