Considered the ‘must-have’ component in most VFD (variable-frequency drive) systems, the AEGIS SGR™ is renowned for improving bearing and motor life. This is achieved by the AEGIS SGR™ safely channelling harmful shaft currents to ground preventing electrical damage.
“The number of benefits the AEGIS SGR™ provides are vast,” explains Martin Deiss Morgan AM&T Sales Manager Germany and AEGIS SGR™ European Product Manager. “What’s more, for us to be able to provide this product, exclusively in our region, is a major coup. The AEGIS SGR™ is a significant enhancement to our product range, and coupled with our industry knowledge and service capability, it will undoubtedly enhance our entire service offering.”
It’s a compelling argument...
Mr Debeuf, Head of Tram Services for De Lijn (Belgium Transport Company) has worked with Morgan to solve a bearing problem using the AEGIS SGR™ and has successfully applied a SGR-11 .2-2 to a traction application. When tested the discharge problem had been eliminated and the bearing life restored.
The AEGIS SGR™ benefits include:
• Fast, easy installation – even in the field
• No machining required
• Mounts on either end of motor shaft
• Simple screw-on mounting brackets
• Unaffected by dirt, grease or other contaminants
• Maintenance free
• Lasts for the life of the motor
AEGIS SGR™
The use of variable-frequency drives (VFDs) to control AC motors has increased dramatically in recent years. In addition to their low operating cost and high performance, they save energy.
Today, the challenge facing system designers and engineers is to minimise damage to AC motors from shaft current. From its first minute of operation, a VFD induces destructive voltages that build up on the motor shaft until they find discharge paths to the frame (ground).
In most cases, the motor bearings present the path of least resistance; once the voltage is sufficient to overcome the resistance of the oil film layer in the bearing, shaft current discharges causing electrical discharge machining (EDM) pits and fusion craters in the race wall and ball bearings.
This phenomenon continues until the bearings become so severely pitted that fluted, excessive noise, and failure occur. The AEGIS SGR™ will prevent this failure by channelling the harmful currents to ground; it is a simple, easily fitted product that should last the lifetime of the motor.
