Balancing and Diagnostic Systems for Complete Cooling Fans
  • Performance measurement
  • Signal analysis of the motor current
  • Vibro-acoustic diagnosis
  • Automatic unbalance measurement
  • Automatic unbalance correction
  • Automatic test sequence

Possible test procedures

  • Signals analysis of the motor current and frequency range for the indentifivcation of commutation errors
  • Signals analysis of the motor current and frequency range for the identification of commutation errors
  • VAD procedure (Vibro-acoustic diagnosis) for objective noise checking through analysis of the structure-borne noise signal in the time and frequency range.
  • Measurement of current, speed and direction of rotation
  • Determining the static and dynamic unbalance with automatic unbalance correction

Special features

  • Single or multiple-channel noise checking with integrated unbalance recognition, optional structure-borne noise checking
  • Powerful industrial PC for control of the test sequence
  • Software module for measurement of performance parameters and VAD procedure and measurement of static unbalance; large rotor type data memory, operator prompting, diagnostic program, statistics, process control, external interfaces
  • Control of brushless motors
  • Correction methods such as nibbling, drilling, coating or milling
