EMI-RFI Filters for OEMs Using VFDs and Servo Drives

As one of the largest EMI-RFI filter manufacturers in the world, Enerdoor offers solutions to customers needing an EMI-RFI filter in conjunction with single or multiple variable frequency drives (VFDs) and servo drives.  

It can be challenging for OEMs, system integrators and distributors to find the proper EMI-RFI filter to use inside a cabinet that has multiple VFDs or servo drives.                    

Drive manufacturers often recommend installing a single EMI-RFI filter for each individual drive. This results in increased cost, more space being used inside the cabinet, and a higher leakage current. Typically, drive manufacturers do not stock EMI-RFI filters, due to the fact they view filters as an accessory and feel they are not responsible for supplying all necessary components in the final system. This tends to make it difficult to purchase these devices.

The Solution
Enerdoor proposes one filter per machine instead of one filter per drive. Using a single filter per machine instead of one per drive offers the following advantages:  

Technical:  Low leakage current; protects the entire machine instead of only the drive. 

Economical: Using only one filter costs less, requires less mechanical space, reduces potential quality issues due to faulty wiring, and accelerates installation time.

The Result
Enerdoor’s unique combination of being an EMI-RFI filter manufacturer and decades of experience with the Enerdoor EMC mobile laboratory has allowed us to comprise a list of filters compatible with the major VFD and servo drive manufacturers of the world. 

All filters listed here have been tested in systems utilizing single or multiple VFDs. If a drive manufacturer is not listed, please contact Enerdoor for the appropriate solution.

EMI-RFI Filters Reduce High Frequency Electromagnetic Noise

EMI-RFI Filters are an electronic device used to suppress conducted interference from a signal or power line. Most electronics require an EMI filter either as a separate device or as a built-in circuit board to reduce high frequency electromagnetic noise between the drive and the mains power supply.

Since 1992, Enerdoor has been a global leader in EMI-RFI filters offering single phase, three phase, and three phase + neutral filters.

Single-Phase EMI Filters Protect The Power Supply

Introduction

EMI-RFI filters are typically installed on the main power line. However, did you know that single-phase filters may also be used to protect the power supply, PLCs, and sensors?  This white paper explains the benefits of using a single-phase EMI filter to protect these types of equipment. 

Switching devices within a machine generate radio frequency (RF) noise which travels back to the power line of the facility. When an EMI-RFI filter is installed, it blocks this RF noise. However, did you know that EMI-RFI filters can also protect equipment from RF interference and voltage spikes that could be coming in from surrounding equipment?  

The Challenge

A power supply requires clean power in order to avoid noise or interference that could affect sensor life or machinery performance. Larger facilities have several different types of equipment which create RF interference and voltage spikes that affect other devices.

Imagine a power supply installed inside a machine located in a large facility surrounded by other large pieces of equipment. How do you think the output supply and sensors are affected?

The Solution

To minimize the risk of interference, install an EMI-RFI filter on the power line. For example, in a three-phase machine application, the filter would protect the entire machine. It would protect the two-phase power line, including the power supply, PLCs and sensors.

The Result

A compact EMI-RFI filter on the power supply input reduces the risk of noise interference in the field and increases machinery life.  Enerdoor is committed to providing the highest level of customer support possible and bringing value to our customers.
