Motor condition measurements are special diagnostic measurements using the Bakker Motor Circuit Analyser (BMCA). This approach has the following advantages:
- no process break with online measurement
- online and offline measurements
- many measurement results in short time
- quick condition assessment
- suitable for any machine type or size
- reduces time required for repair or changing
- compact measuring unit allows flexible use
- registration of measuring results enables easy comparison with trend measurement results
- measurement of frequency control
- measurement from MCC
- pinpointing malfunction location
Zones to be measured:
- power circuit (phase-phase resistance, voltage and current unbalance)
- power quality (voltage, current, harmonic)
- insulation (insulation resistance from windings to earth)
- stator (induction and impedance unbalance)
- rotor (induction unbalance, pole-pass frequency)
- air slit (space between stator and rotor)
