YOKOGAWA ESTABLISHES DIVISION DEDICATED TO IIOT
Yokogawa Electric Corporation has established a new division known as the Architecture Development Division California: an organisation that is dedicated to the development of architecture for the industrial Internet of Things (IIoT). It commenced operations on the 1st November 2016. To improve operational efficiency and productivity by using the IIoT, a robust and flexible architecture is required. For this purpose, Yokogawa has set up the new division to pursue the development of core technologies. It will function as a unit of Yokogawa’s Marketing Headquarters’ Business Development Center, and will keep up with the new technologies being developed every day in the IIoT sector and facilitate close co-ordination with partner companies. Engineers from Yokogawa who have an extensive knowledge of Yokogawa systems and services will staff the division, along with locally recruited engineers who are conversant in a range of IT fields. To start with, the division is located at the engineering office of a partner company, and is
scheduled to open its own office in April 2017. The aim is to add functions for planning services that use the IIoT and cloud computing, and it is expected that the number of staff will increase to around 50 over the next five years. In other news related to the IIoT, Yokogawa
has made a strategic investment in Bayshore Networks, a US technology innovator that is developing cybersecurity software for the Industrial Internet of Things (IIoT). With this investment, Yokogawa will help Bayshore Networks continue development of its IIoT security technology, and will benefit from Bayshore’s communications control and other technologies. The partnership is expected to help speed Yokogawa’s development of the IIoT architecture needed to expand its solutions line-up. This technology has the potential to be a
crucial component in Yokogawa’s IIoT architecture R&D, hence the investment of $900,000 in the company.

THE ‘GREAT EIGHT’ PUT THEIR SKILLS ON SHOW Ann Watson, CEO of Semta, said: “This is a
Eight talented young female engineers have reached the national finals of the sector’s elite competition to be held at the Skills Show at the NEC in Birmingham this month. Semta, the national organising partner for the engineering WorldSkills UK competitions, has been campaigning to increase the number of women engineers working in industry. The ‘great eight’ represents a significant breakthrough for the cause, as there were just four females in last year’s finals – a 100% increase. No less than 44% of the women that entered the 2016 regional heats were awarded a place in the final – compared to 39% of men. All finalists are now battling to be the nation’s best.
major milestone and testament to the work that we are doing to encourage females to enter both the sector and competitions – but it only goes to underline the scale of the problem. “There is still much work in terms of re-
educating parents, teachers and careers advisors. “In order to close the skills gap - it is an
absolute necessity for huge numbers of women to pursue a career in the sector.” The winners of the national finals will be
considered for selection to Team UK – with the chance to represent their country at WorldSkills International in Russia in 2019.

SWEET SMELL OF SUCCESS AT MANUFACTURING EVENT
EEF, the manufacturers’ organisation, has announced that the renowned fragrance designer and entrepreneur, Jo Malone MBE, will be joining its line up of speakers at the National Manufacturing Conference in February next year. Malone will be closing the conference with an inspirational speech designed to end the event on a high. She will be joined by Greg Clark MP, Secretary of State for Business, Energy and Industrial Strategy, and John McDonnell MP, Shadow Chancellor, who are both now confirmed as keynote speakers. The National Manufacturing Conference -
takes place in London on Wednesday 22nd February. It will bring leading politicians, senior industrialists and manufacturing leaders from across the UK together to
discuss the critical challenges ahead. This year it will have a strong global
slant. Key themes up for debate include the UK’s ability to compete globally, UK manufacturing’s prospects in the year ahead, how to make Britain the best place to manufacture and digitising supply chains. Other high-profile speakers include
Martin Wolf CBE, chief economics commentator at The Financial Times, Vicky Pryce of the Centre for Economics & Business Research and Alison Rose, CEO Commercial & Private Banking, NatWest. The conference will also include a new feature this year – Speakers’ Corner – where business experts will offer free tips and advice.

OVERSIZING MOTORS CAN IMPROVE ENERGY EFFICIENCY
When selecting motors for new installations, energy efficiency can sometimes be improved by slightly oversizing the motor, instead of just following a recommendation from a motor sizing tool. Frank Griffith, consultant engineer, ABB, explains...
In the majority of cases, a wider choice of motors is available than the selection tool would have you believe, as each IEC motor frame size offers a variety of options in terms of output and torque. Variations in performance has implications on the internal design, such as the length of the motor core. By selecting a motor with a longer core, the total losses can be reduced. The copper losses increase slightly but the iron losses and the magnetising current are reduced, so the net result is an overall reduction of losses. A slightly oversized motor also increases the
chance that the motor will be running at its most efficient duty, generally 80-90% of maximum torque and 90-100% of the speed. Motors are normally sized using a selection tool such as DriveSize. This will help select an appropriate motor for the duty. However, it may also be worth trying a calculation that oversizes the motor by, say, 15%, to see what happens when the selection tool calculates the overall efficiency of the system. It is possible that efficiency may be improved by
as much as 1-2% by the selection of a motor with a longer core. In the case of motors with long running hours, this will be well worth the effort, as the energy costs over a 30-year life will far exceed the purchase cost. The life cycle cost of an electric motor is much
more important than its purchase price. An electric motor in continuous duty consumes its own cost in energy during the first 30 days, irrespective of its rating. A motor with a longer core will contain more material and so, as a consequence, may cost slightly more to purchase. However, the energy costs over the lifecycle are more significant. A motor that is wasting 1% of its energy over a 30 year life is a poor investment. It must be stressed that oversizing the motor does not produce an energy saving in all circumstances. The outcome depends on the individual installation and the calculation needs to be made on an individual basis.
This way of looking at potential energy savings in motor installations is especially appropriate when selecting motors for long running hours and a long expected service life, such as applications in the water industry or building services, or when designing systems to comply with the energy- related products directive (ErP).
