This series of Armature
Testing Panel is used to test armature for kinds of power tool
and vacuum cleaner. Its LCD show all technical data which obtained by
industrial computer, which check and verify of testing armature.
Feature:
1. All the armature test such as electrical strength (hi-pot), insulation
resistance, DC resistance, welding resistance and between turns of
electrical performance test are done automatically at one time fast.
2. Each test items could be on or off randomly. Approval standard also could be
set up randomly. The machine will give acousto-optic alarm
for reject armature.
3. Identify the malfunction such as between bars short circuit, line cut,
resistance value over limit and give fault point information.
4. Put armature in the optional position, identify winding technical of single
fly, double fly etc and accuracy sorting automatically, auto
track the concerning bar resistance difference, it give alarm when the
coil C.W/CCW hanger direction is wrong.
5. 1/2 station can be chosen (standard model is 2 stations, only for much big
armature, we will design 1 station) with high practicability and testing
efficiency.
6. Customer can do it by programming automatically as per testing requirement.
7. The software give second develop interface, connect the system data base
easily through internet to read- write the data.
8. The software can do far-end control, and merge the testing system into your
company internet to realize the all-in-one.
9. It can save, edit, call kinds model armature and check data specification
automatically. The quantity is unlimited.
Parameter:
1. Hi-pot
(1) Testing voltage range: AC100~2800V
(2) Voltage adjusting mode(-M: Manual adjust; -A: Auto adjust)
a. Manual adjust: manual no-step adjust;
b. Auto adjust: input testing voltage to the software, thus machine do
automatic loading to the setting value through the test.
(3) Voltage precision: ±3%
(4) Capacity: 500VA
(5) Leakage current setting 5 steps(0.5/1/2/5/10mA),
precision: ±10%
(6) Voltage load mode: Between winding and iron core.
(7) OK/Reject verifies way: goods of its leakage current value higher than
setting value is taken as reject. The software will give acousto-optic
alarm accordingly.
2. Insulation resistance test
(1) Testing voltage: DC500V
(2) Testing range: 10~500MΩ
(3) Intergraded accuracy:± 5.0%
(4) Voltage load mode: between winding and iron core
(5) OK/Reject verify way: manual setting the low limit of insulation
resistance, when the goods of its insulation resistance value lower than
setting value is taken as reject. The software will give acousto-optic alarm
accordingly.
3. Cold resistance test
(1) Testing range:
(a) 0.001~0.999(resolution ratio 0.100u Ω
(b) 1.000~9.999(resolution ratio0.010mΩ )
(2) Precision: ± 5.0%auto temperature compensate, could be calculated to
resistance value at20℃.
(3) Testing way: between armature stamping and stamping.
(4) OK/Reject verifies way: Program reads the testing value of winding and
verifies ok/reject by comparison of upper and low reference
value. The software will give acousto-optic alarm accordingly when it's
rejecting.
(5) The software search out the minimum value of testing resistance
automatically, auto rank ordering and resistance self-learning function.
4. Welding resistance test.
(1) Testing range:0.001~0.999(resolution ratio0.010mΩ )
(2) Precision: ± 5.0%auto temperature compensate, could be calculated to
resistance value at20 ℃.
(3) Testing way: use sis ends method, testing the resistance value of
commutator segment and winding welding point.
(4) OK/Reject verifies way: Program reads the resistance testing value of
welding and verifies ok/reject by comparison of
upper and low reference value. The software will give acousto-optic alarm
accordingly when it's rejecting.
5. Between turns insulation test
(1) Testing voltage range: 100V~2800V
(2) Voltage precision:±3.0%
(3) Voltage adjusting mode(-M: manual adjust, -A: auto adjust).
(a) Manual adjusts: Manual no-step adjust
(b) Auto adjust: input testing voltage to the software, thus machine do
automatic loading to the setting value through the test.
(4) Pulse rising time: 1.2μS
(5) Verify way: s/sf/f
(6) Voltage load mode: respectively test each winding.
(7) OK/Reject verifies way: Program reads the standard value of wave between
turns, compare the testing wave to standard wave. The software
gives acousto-optic alarm if beyond setting value.
