Design Features:

Machine frame with unbalance measurement and test equipment.
Protective housing with wide loading doors.
Integrated measurement and control cabinet with a test computer and power unit.
Two-station machine with manual loading, automatic test sequence, and unbalance correction.

Test Procedures:

Motor current and frequency signal analysis for commutation error identification.
Vibro-acoustic diagnosis (VAD) for noise checking through structure-borne noise signal analysis.
Measurement of current, speed, and rotation direction.
Static and dynamic unbalance measurement with automatic correction.

Special Features:

Single or multiple-channel noise checking with integrated unbalance recognition.
Powerful industrial PC for test sequence control.
Software for performance parameter measurement, VAD procedure, and static unbalance measurement.
Control of brushless motors and correction methods like nibbling, drilling, coating, or milling.
