Enerdoor's Motor Protection Snubber Range by GD Rectifiers

Enerdoor’s latest product development, the FIN47SNB snubber benefits markets facing voltage wave reflection issues due to their use of variable frequency drives. Voltage wave reflection is a function of the voltage rise time (dV/dt) and the length of the motor cables. This sensation creates additional overvoltage spikes causing premature degradation and failure to motor insulation and bearings.

 

The Challenge

It can be challenging for OEMs and system integrators to ensure the installed motors are well protected. Markets using a variable frequency drive (VFD) can often negatively affect the longevity of the motor, in particular the winding insulation and bearings.

Enerdoor’s Solution

Enerdoor’s objective was to create a solution, utilising low power loss, in order to maintain the overvoltage spikes. Enerdoor’s snubber FIN47SNB is a unique solution that is designed to reduce common mode and differential mode noise. The snubber is used in parallel to the system and is an ideal solution for clients in need of improving the reliability of winding insulation and bearings.

Enerdoor’s unique solution featured in FIN47SNB, snubber protects any type of motor configuration, including: 3-phase, 3-phase plus ground and 3-phase plus star point plus ground. The parallel concept allows for easy installation in new or existing applications. The FIN47SNB is a highly reliable product due to the fan, remote indicator and thermic pad.

Unlike similar products, the FIN47SNB is able to protect both winding insulations and bearings at the same time. The Enerdoor snubber is recommended to be installed in close proximity to the motor. For applications with short motor cable <10 metre (30 feet) between the drive and motor, the Enerdoor snubber can be installed inside the cabinet in parallel to the output side of the VFD.
