How to select the best material for an electrical enclosure
At first glance electrical enclosures are simple boxes, but choosing the best material of construction from the many available requires some consideration. Chris Lloyd, Managing Director for Spelsberg els UK, offers some advice.
How to guarantee accuracy throughout the manufacturing process
For want of a nail the shoe was lost. For want of a shoe the horse was lost. This proverb carries on through rider and message to battle and kingdom. It pre-dates modern manufacturing – probably by a couple of centuries – but exactly the same principle applies to engineering. Chris Putman, Sales and Marketing Director of WDS explains that if you don’t get the small details right, the big picture will never be perfect.
Staying ahead of the motor efficiency standards
From January 1st 2015 the latest efficiency regulations for electric motors come into force in Europe whereby any new installation using a motor between 7.5kW and 375kW must use either an IE3-rated motor or an IE2 motor installed with a variable frequency drive (VFD). Aimed at improving the overall efficiency of the installed equipment across Europe, the regulation is supported by a new standard, EN50598, which benchmarks the efficiency ratings of electric motor drives.
Vibration analysis: save time, money and your reputation
Dr Steve Lacey, engineering manager at Schaeffler (UK) Ltd, describes how the operational testing of wind turbine gearboxes can help to identify potential gear- or bearing-related problems prior to installation, saving the customer time, money and their reputation.
SATO helps food businesses comply with EU legal obligations
SATO has developed systems that produce labels to clearly indicate vital information about foods and beverages, enabling food manufacturers and retailers meet EU legal obligations and avoid harsh penalties. With the new European Directive 1169/2011 on food labelling coming into force on 13th December 2014, anyone producing or selling foods and beverages without clearly displaying information such as allergens, nutrition and origin may be at risk of criminal prosecution. Although they differ from country to country, penalties are likely to be severe and range from unlimited fines in the UK to up to 2 years in prison in France.
Extension and compression springs machined from solid material
This article from Abssac explains some of the physics behind machined springs, and how this translates into real-world advantages.
Thermal management: life lessons for electric motors
Improving the efficiency of electrical conversion and new methods of thermal management may mean that in future motors run far cooler than they do today. But until then, heat dissipation remains a major consideration for designers of motor-driven systems. Bill Bertram, of motor maker Marathon Electric, looks at the state of the art and casts one eye into his crystal ball.
Robots helping food processors future proof their plants
People need to eat, so there will always be a food industry. But people are also demanding, so price, quality and availability are the main forces that drive development in the industry. Ten years ago UK food prices were far lower than they are today – and since the bank collapse of 2008 many people have lower incomes. Food processers are aware of this and are increasingly looking to robots and automation to address their operating efficiency.
