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
