Brushless dc motor factory comprehensive performance test system
1, the brushless dc motor factory integrated test system test items include: electric strength, insulation resistance, to launch the test motor speed; The rated power (Voltage, current, power), undervoltage protection, overvoltage protection, speed test, to judge, vibration test, FG feedback signal test.
2, test mode: automatic test: press on the operation panel & other; The left workstation & throughout; Button or & other; The right location & throughout; Button or click on the software & other; Automatic test & throughout; Can be automatic testing, the system will test for each project, until completion of the project measurement, then stop. Manual test: test button click on the software on a single project, the system will be carried out in a single project test, brushless motor, after the test.
3, test content:
(1)Electric strength (Pressure)Measurement of the motor input L, N (Including the motor drive)And GND (The shell)Between the pressure;
（2)Of the motor insulation resistance test input L, N (Including the motor drive)And GND (The shell)The insulation resistance between;
（3)Motor speed test: the tested motor drive through working voltage (firstAC220V）； Simulation to control the output voltage of 0 v after 0 ~ 5 s after several analog voltage, set time adjust the start control signal voltage (Such as DC10V)； Collection and motor voltage, current, power, speed, vibration test at the same time. FG feedback signal
(4)Motor turned to the test, the tested motor drive through working voltage (firstAC220V）To a cylinder; Simulation to control the output voltage of 0 v after 0 ~ 5 s by the upper machine set the start line voltage (Such as DC1V)To begin, the motor rotation (Test to)Disconnect the power supply (AC220V）。
（5)Over voltage test: the tested motor drive through first overpressure test voltage (AC250V)； Waiting for 0 ~ 5 s (The control voltage of 0 v)Set by the upper machine after starting line voltage (Such as DC3V), collecting voltage current power, judge whether the control signal protection action, plant protection unmanned aerial vehicle (uav) motor, stop to stop the control signal, the power off.
（6)Under voltage test: the tested motor drive through first undervoltage test voltage (AC180V）； Waiting for 0 ~ 5 s (The control voltage of 0 v)Set by the upper machine after starting line voltage (Such as DC3V), power acquisition voltage current, judge whether the control signal protection action, stop to stop the control signal, the power off.
（7)FG under motor speed feedback signal detection; Control signal to stop testing done first, then power off.
