Retrofitting filters to your variable frequency drive (VFD) What is RFI filter in VFD? EMI Filters, or electromagnetic interference filters, also called RFI Filters or radio-frequency interference filters, are an electrical device / circuit that mitigate the If the noise is coming from the filter then replace the filter, next would be the VFD and last, the motor. This is obvious but the VFD noise and the signal range overlap so I could potentially cut off my signal. Unfiltered VFDs generate harmful harmonics—this leads to motor failures, miscommunication in control systems, and costly downtime. They help machine builders meet the CE machine directive for filtering.

This noise can disrupt other electronic devices and cause compliance issues with regulatory standards. The input stage of a Variable Frequency Drive (VFD) often generates undesirable harmonic distortion, but this issue can be mitigated effectively by implementing a harmonic filter. EMI filters target high-frequency electrical noise while harmonic filters address power harmonics at much lower frequencies (<400Hz). A reactor doesnt do anything with the noise pulse, an RC filter 'eats ' it, makes it disappear (the resistor Servo / VFD EMI filters help to substantially reduce EMI in the equipment and to protect motor's bearing from EDM-caused fluting. There are several sub-components within the VFD and motor which are sensitive to An EMI line filter will use resistors, inductors (about 100 uH) and capacitors to filter out noise that would flow back up stream into the 60 Hz or 50 Hz sinusoidal power supplying the VFD.
