How To Judge The 20 Slots Heating Motor Armature
With four aspects
1. Bar to Bar resistance,0.01mΩ~10mΩ (Out of range display OVER)
Four-terminal measurement to ensure accuracy
2. Welding resistance,0.001mΩ-10mΩ (Out of range display OVER)
Six-terminal measurement to ensure accuracy
3. Cross resistance 0.01mΩ-10mΩ
Four-terminal measurement to ensure accuracy
4. Surge 100-1000V (100V/time)
Pulse crest:0.5u sec, Frequency 1~40MHz
Standard waveform is Write, OK waveform is Green, NG waveform is Red
5. Isolation resistance DC 500V
Testing time:1~10s (0.1s/time)
Range:1~500MΩ
Accuracy: ≤±5%
6. Hipot AC 100-1000V
Testing time:1~10s (0.1s/time)
Armature commutator bars ≤ 36 bars
Testing panel cycle time: 8~9s (according to 33 bars)
Motor Manufacturer Question and Wind Automation Answer
Motor Manufacturer K from Turkey
During welding resistance measurements on a 20-bar commutator, I generally obtain values between 0.02 mΩ and 0.04 mΩ. However, occasionally, I encounter values around 0.3 mΩ on some commutator bars.
Could you please advise what the maximum acceptable welding resistance should be in such cases? For instance, would setting a maximum limit of 0.1 mΩ be appropriate?
How can we calculate or define a proper threshold for this parameter?
Wind Automation Reply
The maximum acceptable welding resistance would setting a maximum limit of 0.1 mΩ is appropriate,
When the welding resistance is 0.3mΩ , the motor will be risk of burning which is caused by high current as a high resistance,
