- Abstract:
- In this paper, new criterion for evaluation of endangerment of bearings due to bearing currents – the trend line of the Joule integral of bearing current - is proposed. Suggested is the measurement procedure for bearing currents with selection of appropriate sensor. An analysis, which is the basis for selection of current sensor for bearing current measurement, is presented. The shunt sensor as most appropriate sensor was implemented into measurement procedure and experimental measurements were performed on 1.6 kW brushless direct current (BLDC) motor.
