As the legislation surrounding the efficiency of electric motors continues to tighten, the volume of variable speed drives (VSDs) in service increases. Often specified by the motor manufacturer as part of the original installation – or retrofitted to improve efficiency – the drive contains both hardware and software that is designed to work with a motor in a specific application. So, what happens if the drive ceases to operate? Brian Park, Regional Sales Manager for Scotland at Sulzer, looks at the advancing technology and the maintenance processes that need to keep pace.

Manufacturing, utilities, and oil & gas companies have been gathering troves of raw data since well before the Internet of Things was a thing. For decades, machines like pumps have collected big analog data about voltage, motion, sound, acceleration, vibration, and more at the farthest reaches of the network. But industries have never had the compute power and technology to process that data and turn it into real-time, data-driven decisions at the “edge” (on premise, away from the data center and closer to the “things”) —until now.
Sulzer operates one of the most comprehensive maintenance, repair and technical support services for large capacity motors and generators worldwide, providing everything from testing to complete re-builds. Owners and operators of three-phase asynchronous motors manufactured by Franz Wölfer Elektromaschinenfabrik can now call Sulzer from anywhere in the world to assist with the repair and maintenance of their motors, safe in the knowledge that the service is fully supported by the manufacturer.
President of Rotating Equipment Services at Sulzer, Peter Alexander, ‘‘We have worked hard to establish a network of service centers at strategic locations around the globe where we can service any large motor or generator. These specialist manufacturing, engineering and test facilities are supported by highly trained installation and commissioning teams that can provide service onsite anywhere around the globe, including during active service out at sea. This agreement with Wölfer is a great opportunity to benefit all their customers.”
Plant and maintenance engineers often seem to have an intuitive nose for trouble, so are able to predict pending problems with machinery and take pre-emptive action to prevent them. It is not the result of magical powers, rather of long experience with plant and machinery. Bill Bertram of motor maker Marathon Electric explains how different motor sounds can be interpretedÖ: “If you walk around a piece of plant that is running, you will hear it making a noise. If you listen carefully you will be able to pick out individual elements within the overall sound. For instance, you may be able to hear a fan whirring, a pump thumping and a conveyor rumbling.”
The new EZ-Install TPE Diaphragms have been designed so that the operator in the field does not need to invert the diaphragm during the installation process. This improvement will reduce the installation time, lower maintenance costs and improve uptime. A short video of the EZ-Install Diaphragms can be viewed here:
