Description
Technical field
The utility model relates to a kind of motor, specifically a kind of motor detection apparatus.
Background technology
The parameter of electric machine self-test device in existing speed regualtion of AC motor field, is made up of control panel, drive system main circuit and alternating current generator: main circuit provides the Energy transmission of drive motor usually; Control panel controls the Energy transmission of main circuit by controlling driving switch signal, thus controls the amplitude of the input voltage of alternating current generator and frequency, and samples to the signal obtained by voltage-current sensor.Voltage and current value that final control panel obtains by sampling, calculate the corresponding parameter of electric machine according to alternating current generator circuit model.
The above control panel is made up of MCU (microcontroller) and voltage sample, current sample, fault detect and driving circuit: voltage, current sampling circuit process the sampled signal obtained from voltage/current sensor, obtain the signal that MCU can receive identification, thus make MCU obtain voltage, current value; Driving circuit is by the output control switch instruction transformation of MCU
For drive singal, thus the output of control system main circuit, drive alternating current generator; Failure detector circuit detection failure signal (as overvoltage, overcurrent etc.) also delivers to MCU; MCU carries out control algorithm and fault handling.
But in the application process of existing parameter of electric machine self-test device, designer finds prior art, and there are the following problems:
In the existing parameter of electric machine Autonomous test technical scheme voltage sensor and sample circuit cost higher, and voltage sampling circuit postpone cause the error of calculation, cause the error of calculation of the parameter of electric machine, obtain the inaccurate parameter of electric machine.
