High Efficient Stator Testing System Of Brushless DC Motor DD Motor
Stator Test
1. Test overview
1.1 Tested object: stator of the washing machine motor with outer
rotor
1.2 Test items:
AC Hipot, insulation resistance, surge, winding resistance,
inductance, back EMF, Hall, rotation, Back EMF
graph, Hall graph
2. System introduction
Composed of test bench, industrial computer, master unit, control
software and some function modules,
the panel can be used to test the safety, parameter and back EMF
test for the outer rotor. Start the
testing panel, and the back EMF and Hall can be tested in sequence.
The pass or fail signal will be
triggered after completing the test.
Equipped with industrial computer and Windows operating system,
professional control software, the
panel can be operated easily.
3. Main features
Innovative design makes the operation easier
Designed as to the production line requirements
Adopt simple and high efficient clamping mode
User permission setting function
Large storage space saves the testing parameters and data
Support connection with the MES system
Support remote control software upgrading
