armature testing machine specially design for
wound armature which is with commutator pressed.

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 ratio 0.010m Ω )
(2) Precision: ±  5.0%auto temperature compensate, could be calculated to resistance value at 20ºC.
(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 ratio 0.010m Ω )
(2) Precision: ±  5.0%auto temperature compensate, could be calculated to resistance value at 20 ºC.
(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.
