1.Efficiency
Two working positions, 1 pc/10second for 24 segments commutator armature.
2.Aplication:
Suitable for testing less than 24 segments armature
3.Main fuction
1-Automatically test by computer
2-Dynamic simulating test process, synchronously display testing data.
3-Voltage withstand test time could be set as per different requirements
4-Armature part number and testing criterion could be input and saved manually
5-Testing items could be screened
6-Testing data saved automatically, and could be traced and printed at any time
6-Testing data saved automatically, and could be traced and printed at any time
7-Alert by sound and lighter when parts rejected
4.Main configuration
1-Tester Max dimension: 850(width)*950(depth)*1870(height),surface plastic blast, white color computer. Electric cabinet in good ventilation condition and mouse proof.
2-Two working position could rotary test. The height of working position is 790mm,working station dimension is 460(depth)*800(width)
3-Computer system with CPU1.3G,internal save capacity 128M,harddisk 80G,15"colorful display screen
4-Connector and sampling circuit from Japan and U.S.A
5-Windows 2000 operation system
6-two sets pneumatic testing fixtures(each for left and right position)
5.Testing item and technical data
1-Electric strength (high voltage between core and winding)
Testing condition AC 0-3000V adjustable
Voltage tolerance ±3%
Current leakage flow distance 0.1-10mA
Current tolerance ±1%
Time 1s~60s(could be set)
2-Insulation resistance (between winding and core)
Testing condition DC 500V
Range 10MΩ-2000MΩ
Tolerance 10MΩ~200MΩ ±3%
(ignore tolerance when more than 200 MΩ)
3-Bar to bar resistance
Histogram display bar resistance,and testing data could be aligned in sequence, it is easy to know the winding aligned direction
Testing range: 0.001-200Ω
Tolerance: ±1%
Temperature compensation: 20℃
4. Welding resistance:
Histogram display bar resistance,and testing data could be aligned in sequence,
Testing range: 0.01-100mΩ
Resolution: 1uΩ
5. Turn to turn resistance
Could set testing bar number at random, realize turn to turn testing function for winding of each bar
Pulse voltage peak value 500-3000V DC
Pulse peak value tolerance ±5%
Criterion value setting conclude as per the percentage of △S and △f,setting range is 1%-99%
