Insulated Automatic motor stator Testing Machine Cold Resistance 500va Capacity

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%
(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 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.
