Production Line Stator Testing System For Home Appliance Air
Conditioner Motor
1. Test object: stator of home appliance air conditioner motor
2. Test items:
AC Hipot, Insulation resistance, surge, winding resistance and
direction of rotation
3. Equipment outlook:
3.1 Equipment dimension: height 1405mm * width 660mm * depth 840mm;
3.2 Dual station, and the supplier provide the test bench.
3.3 Integrated test bench, enclosed protective cover
4. Reference Picture of the stator testing system (the test bench will be designed as to the stator
that need to be tested)
5. Function description
5.1 All the test items can be selected by the operator
5.2 Over 1000 motor models can be established by the operator.
5.3 The parameters range for each type of motor can be entered and
saved. The inductance and
resistance test has the function of setting and displaying the
unbalanced degree.
5.4 “Continue to test” and “stop the test” can be selected if the
stator fails the test. If the stator fails the
winding resistance test, the test will be stopped until testing all
the three windings.
5.5 The testing data can be exported via USB interface.
5.6 User administration setting can avoid the parameter setting by
misoperation.
