S1: for motor provide 1.5v dutycycle be 50% operating voltage, simultaneously detect 1.5v work time motor rotating speed, object is the motor filtering out poor starting; This process circulates 3 times.
S2: for motor provides continuous print 3v power supply, detects the supply voltage of motor, electric current, DC impedance, running speed and the both positive and negative polarity insulation situation to motor case simultaneously.This process is to judge whether tested motor has the situations such as the bad and electric leakage of open coil, short circuit, rotor lubrication.
S3: for motor provides 3v power supply, detects the operation waveform of motor under this voltage and sound spectrum simultaneously, this process be to judge the waveform of motor bad with sound spectrum during motor running whether in setting range.
Detected parameters can adjust at any time as required on touch screen.
What finally illustrate is, above preferred embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model by above preferred embodiment, but those skilled in the art are to be understood that, various change can be made to it in the form and details, and not depart from the utility model claims limited range.
