Stator Vacuum Testing Machine Of Brushless DC motor On Automotive Pump
1. Test object:
Stator of brushless DC motor on automotive pump
2. Test and introduction
AC Hipot (winding to iron core), insulation resistance (winding to iron core), surge, DC resistance, rotation (phase)
3. the importance of Stator Vacuum Testing
As the quality-guaranteed industry, automotive motor has higher requirement towards test.The automotive pump motor has changed to brushless motor gradually. Therefore, the test technology is changing as well. The stator faulty coil is easily to be detected under vacuum testing environment.
