capable of testing a VFD's two remaining operational modes: acceleration and deceleration. To address this, it was necessary to connect a modern motor test instrument capable of monitoring VFD applications—and these two additional modes. Figure 2 and Figure 3 are screen captures from the display of an SKF EXP4000 dynamic motor analyzer [16].
Circulating bearing currents—related to VFDs—are primarily caused by the speed of the inverter switching in the output stage of a VFD. Drives use Pulse Width Modulation (PWM) with semiconductor circuitry to generate the variable frequency and voltage to power the motor at variable speeds. This high switching rate induces a voltage on the ...
