Baxters Food Group had been using a Danfoss 18.5 KW drive at its Colchester site; however, it had failed completely. There had been reports of a strong burning smell and a loud bang from one of the stainless-steel agitator bowls used to mix a variety of sauces. Subsequently, the industrial mixer in question had stopped working entirely due to water ingress in the drive.

A drive engineer from Gibbons Engineering Group was sent to the site to find out what was needed to resolve the issue; a simple repair or a complete replacement of the drive in question. On arrival, the engineer liaised with the site manager and investigated the problem. It was decided that a complete upgrade of the drive system was needed. After removing the old unit, a new, fully optimised ABB 18.5KW ACH550 inverter was retrofitted to the existing panel.

Before beginning the work, a brief history of the machinery was given to help make things run smoothly. The failed drive was large and took up a lot of space, but the new replacement ABB drive is much more compact and has more functionality. The installation was a straightforward swap, and once completed, the engineer instructed the team at Baxters on how to use the drive correctly, as they were previously having trouble setting the drive to a slower speed.

On power-up, a minimum and maximum speed were pre-programmed so that the operators could adjust the span via the ten-turn potentiometer. The new drive is being used to mix different sauces, hence the need for varying speeds.

Once the drive was successfully installed, the machinery was fully tested before sign-off with the customer.

Around the world, businesses, innovators, policymakers, and cities are recognising that our take, make, waste linear economy – in which finite resources are extracted to make products that are used, generally not to their full potential, and then thrown away – is no longer working for people or the planet.

Given the speed at which our government changes policies these days, I'm hesitating to make any comments in this quarter's update for fear of it being outdated by the time it is is published. We are at the beginning of a new year, and there will be many new opportunities to watch out for. It's also a good opportunity to take stock of the last 12 months and reflect on what was another remarkable year for our industry.

Against a backdrop of increasing energy costs, significant savings can be made by upgrading old motors to more efficient modern alternatives. However, simply swapping a motor for a modern equivalent is not always practical or even possible. With this in mind, Thomas Marks, General Manager and Secretary at the Association for Electrical and Mechanical Trades, looks at how a motor's efficiency can be improved as part of a repair or refurbishment and highlights some things you should consider.
