  • Page 16: Frequency Converter Operation

    7.3 Frequency converter operation In principle, all three-phase motors can be connected to a frequency converter. However, frequency converter operation often exposes the motor insulation system to a heavier load and causes the motor to be more noisy due to eddy currents caused by voltage peaks. In addition, large motors operated with a frequency converter are loaded by bearing currents.
