VFD

Are You Correctly Applying Line & Load Reactors on VFDs?

Today’s electronic equipment requires clean, consistent power for optimal performance.  The presence of power distortions between VFDs and motors can damage equipment, jeopardize productivity, and decrease profitability. We see line and load reactors are often applied on AC variable frequency drives (VFD) without a solid understanding of when and why they should be used. VFDs […]

LUTZE DRIVEFLEX® Cable for VFD and Motor Applications

Variable frequency drive (VFD) cables have distinct advantages over traditional cables when used in drive and motor applications. When installed properly, VFD cables reduce cross coupling between drives and the shield contains and drains the electrical noise created by the drive. Their noise mitigation helps with the proper function of adjacent control systems and they […]

Electric Motor Bearing Failure and Use of the Proper VFD Cable

What causes bearing failure to occur between the variable frequency drives (VFD) and electric motors?  What can be done to minimize the potential for failure? For starters, the ball bearing is the connection between the shaft and the motor frame.  There are two rings: an inner ring (which is in contact with the shaft) and […]
