Rotor position sensor test stand for fault pattern analysis
- Type: development test stand
- Device under test: rotor position sensor for electric motors
- Test task: influence of various fault patterns on measurement accuracy
Rotor position sensors are essential for determining the position of electric motors precisely. Motor control and efficiency depend on them working correctly. In practice, though, misalignment and deviations occur, caused by manufacturing tolerances, assembly errors or mechanical loads.
Detecting and compensating signal distortion and measurement errors early requires a detailed analysis of these fault patterns.
Typical test requirements:
✔ Exact simulation of fault patterns (eccentricity, tilt, distance deviation)
✔ Repeatable test conditions for precise analysis of signal distortion
✔ High accuracy for minimal measurement deviation
- E-mobility
- Automotive
- Development
Benefits at a glance
- High-precision fault pattern simulation: exact setting of eccentricity, tilt and distance deviation
- High repeatability: precise control and documentation of all test parameters
- Flexible: suitable for different designs and sensor concepts
- Easy-to-use software: guided test sequences with real-time analysis
Test tasks
- Eccentricity simulation: offset of the rotor center from the axis of rotation
- Rotor tilt: effect of a wobbling target on measurement quality
- Distance testing: analysis of position deviations in X, Y and Z
- Sensor angle deviations: simulation of pitch, yaw and roll of the stator
- Signal distortion analysis: effects on the measurement signals
