End Of Line for testing the behavior of brushless motors.
The motors pass 6 different test stations on workpiece carriers transported by a belt system.
BEMF station: Measuring and evaluating the electrical properties of the motors (hall-, optosensors, winding properties).
Run-in station: Burn-in test to spread the grease inside the bearings in order to achieve more stable running and easier start. Another goal is to face the motor with heavier conditions.
Vibration station: Measures the motor vibrations under real conditions (analysis software in collaboration with the University of Ljubljana).
Imbalance station: Measures the imbalance of the motors under real conditions (collaboration with an external imbalance specialist) .
Torque station: Measures the torque of the motors while stressing them with an eddy current brake.
Run-out station: Measures the concentric of the motors relative to the center of rotation via Keyence 2D-Micrometer.
