The binding post is provided with multiple.
The utility model has the beneficial effects that damage of the utility model using loss analysis and input-output method measurement motor
Consumption value;In operation, it first treats measured motor to be checked, then verification nameplate data etc. are measured cold conditions direct current to motor
Resistance, cold conditions instrument for measuring DC resistance device mainly include resistance measuring instrument, temperature measurer;Heat test is then carried out, heat test is main
Including equipment such as digital power table, torque-speed measuring device, temperature measurer, resistance measuring instruments;Load test is carried out later,
First the disengagement that couples of load motor and sensor, start to measured motor and belt sensor apparatus working, electric moter voltage to be measured
It is adjusted to rated value, to torque rotary speed sensor rezeroing, and saves zeroing result;Load motor is connected again again to start to carry out
Load test;It when test, should keep being changed to voltage rating, rated frequency to measured motor, load is adjusted from high to low;Finally
No-load test is carried out, is mainly completed by equipment such as digital power table, temperature measurers;Finally the data being collected into are handled;
Since this instrument has data acquisition equipment, digital power table and ARM control mainboard, data can be not only collected, but also can
Data are analyzed, result is finally directly displayed to the trouble for avoiding follow-up data processing on a display screen;And by repeatedly examination
It tests, keeps measurement result more acurrate;When operation, also corresponding the end of a thread need to be only connected on corresponding binding post, so that it may complete test;
To sum up, the utility model has the advantages that operation is scientific, easy to operate, data processing is quick.
