1 Technical data
AC withstand voltage test (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%
(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 vertify way: goods of its leakage current value higher than setting value is taken as reject. The software will give acousto-optic alarm accordingly.
Insulation resistance test:
(1) Testing voltage: DC500V
(2) Testing range: 10~500MΩ
(3) Intergrated accuracy: ± 5.0%
(4) Voltage load mode: between coil 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.
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 20℃.
(3) Testing way: between armature stamping and stamping.
(4) OK/Reject verify way: Program reads the testing value of winding and verify ok/reject by comparison of upper and low reference value. The software will give acousto-optic alarm accordingly when it's rejected.
(5) The software search out the minimum value of testing resistance automatically, auto rank ordering and resistance self-learning function.
Welding electrical 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 ℃.
(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 rejected.
Between turns insulation test (Surge):
(1) Testing voltage range: 100V~2800V
(2) Voltage precision: ±3.0%
(3) 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.
(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.
This machine is used to test armature for kinds of power tool and vacuum cleaner.
3 Machine main function and characteristic
1. All the armature test such as electrical strength, 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, identity winding technical of single fly, double fly ect 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. Single station/double station can be chosen, with high practicability and testing efficiency.
6. Customer can do item 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.
