10‘‘ colour touchscreen: 1805 & 1886 series
Modern digital technology for safety-current-limited applications or those at 500 VA / 200 mA.
PC controlled test system with large test cabin for stators and complete e-axles of electric sports cars of the future.
Industry: Automotive industry / electric motors
Stators and e-axles for electric sports cars must be checked for function and safety before installation. In order to be able to test small stators up to complete electric axles, the largest possible test station is required. A complete pre-series test should be realized in this way.
A test system with a double-leaf safety door was developed. The fully insulated interior offers sufficient space for all kinds of DUT. The safety test technology is housed in a mobile 19“-ESD test cabinet. The contacting is done via test adapters with interfaces for winding and temperature sensors. By scanning a DMC code attached to the DUT, the correct test program is automatically selected from the database. By closing the door and pressing the start button, the test program is started and runs fully automatically.
– Measurement of the ambient temperature (if necessary the winding temperature)
– Resistance measurement of the windings including symmetry analysis and temperature compensation to 20°C
– Resistance measurement of the temperature sensors including temperature compensation to 20°C
– Inductance measurement of the windings including symmetry analysis
– Insulation resistance test of the 3 phases against housing
– High voltage test AC / DC between the 3 phases and housing; Ramp freely adjustable
– Surge test including partial discharge measurement and rotor alignment
– Potential equalization measurement at 5 freely selectable points
