Industrial alternator launched.

The LSA 47.3 industrial alternator offers increased efficiency and starting kVA over its predecessor, and also benefits from the implementation of the lastest technologies developed by Nidec Leroy-Somer.

"The LSA 47.3 is an important step forward in our strategy to optimize our product range" said Wenbin Ding, low voltage range product manager "The benefits of this new product are significative, with real improvements where it matters most: efficiency, power and starting kVA. In addition, the optimized cooling system we implemented means that hot spots are reduced inside the machine. Ultimately this means a better reliability and longer lifetime, which is essential for the applications all LSA alternators are built to support.”

The LSA 47.3 delivers a rated power between 410 and 660 kVA at 50 Hz (495 to 825 kVA at 60 Hz). The 660 kVA rating (825 kVA at 60 Hz) was previously held by the LSA 49.3. Thanks to the cooling circuit optimization, the LSA 47.3 is now able to reach this power node for prime and demanding application. This is a significant benefit for generator set manufacturers as the same power is made available through a more compact machine.

The LSA 47.3 alternator features a SHUNT excitation system with a R250 regulator as standard. An AREP auxiliary winding excitation system with D350 digital regulator version is also available to improve transient performances and provide high overload capacities. A D550 digital regulator can also be used for grid connected applications. A Permanent Magnet Generator (PMG) excitation system is also available as an option.

The LSA 47.3 is fully interchangeable with the LSA 47.2 (shaft height and feet configuration), and can therefore be coupled with all diesel engines on the market for this power range. It is now available for orders. 

The LSA 47.3 offers the following power nodes: 410, 455, 500, 550, 600, 660 kVA at 50Hz 510, 570, 625, 690, 750, 825 kVA at 60Hz

This alternator is optimized for prime and demanding applications such as marine and cogeneration. It offers an efficiency of up to 95.7% at cos φ 0.8, which ranks it among the best in the category.

With the LSA 47.3 introduction, the LSA 47.2 will soon be retired from the market, as well as the LSA 49.3 S4 (660 kVA).

Green go-kart in education!

At the University of Southern Denmark (SDU), engineering students are taught electronics and challenged with real-life industrial equipment driven by electric motors and drives manufactured by Nidec.

SDU gives young engineering students an opportunity to be part of developing the green technology of the future in a creative study environment with modern teaching facilities and dedicated teachers.

The students have access to a genuine go-kart 

The use of high-tech technologies in the form of real-life industrial equipment and advanced electronic techniques is an important part of the teaching and education of Denmark’s future electronics specialists. As part of the teaching projects, the institute and the students have access to several advanced electronic test benches, which gives them a good insight into the handling, testing and research of different combinations of industrial electronic equipment and teaches them to test torque, speed, load, etc. under realistic conditions.

The test benches combine different set-ups of advanced variable speed drives and high-tech electric motors, which have the flexibility to test a wide variety of electronic equipment. The test benches use Nidec Leroy-Somer motor units (servo motors, LSMV and IMfinity induction ranges) and Control Techniques Unidrive M600/M700 drives.

Each semester, the electronic engineering degree programme includes project work on a current topic, for example how to design the electronic controller of an electric go-kart motor. In the course of the project, the students work with the design of variable speed drives, programming, modulation and simulation of the drives as well as the design of electronic hardware. The students have access to a genuine go-kart with an electric motor as well as a corresponding test bench with programmable drives and electric motors.

All in all, the realistic project provides useful knowledge and intuitive understanding of the control of electric motors, which can also be used in connection with variable speed drives for electric cars,
robots, etc.

Chief visits new acquisitions.

The founder and CEO of Nidec has visited Control Techniques and Leroy-Somer to outline his vision for the future of the businesses.

Carwyn Jones, Prif Weinidog Cymru.

Shigenobu Nagamori, who launched Nidec in Kyoto, Japan in 1973, presented to Control Techniques and Leroy-Somer staff at their respective headquarters in Newtown (GB), and Angouleme (F) on February 2 and 3. The events were simultaneously broadcast to Control Techniques and Leroy-Somer staff across the world. (see our report Acquisition Completed 3/2/12017)

Mr Nagamori spoke about the opportunities presented to both businesses, and was positive about the impact Nidec could have in the future. Questions were invited from existing staff members regarding investment, job security and proposals for future growth. The First Minister of Wales, Carwyn Jones AM, attended the event and met with Mr Nagamori to discuss the future of Control Techniques in Wales.

Mr Nagamori said: “We are pleased to welcome Control Techniques and Leroy-Somer into the Nidec family. We have strong ambitions for both companies to grow, and Nidec is committed to providing the necessary support and investment to make that happen.

“Industries which require the use of electric motors, and therefore drives, will form the backbone of the world’s economy in the future. Look at the expansion in the use of robots, electric vehicles and drones. All these items need motors, and all those motors need drives. There are clear opportunities for Control Techniques, Leroy-Somer and ultimately Nidec to prosper here.

“Our policy is to put the systems in place which will encourage growth. We will hire and train high calibre people, and encourage those already working for the businesses to enhance their abilities.

“We will put great emphasis on research and development. As an R&D engineer myself, I know that it is technology which will ensure our businesses succeed.

“Control Techniques, Leroy-Somer and Nidec offer each other great synergy, and working together we can improve and make our goals a reality.”

Nidec boasts a strong track record of facilitating growth among its business, through investment in engineering, design and resources. It has also demonstrated a clear strategy to drive growth in both companies, as well as providing considerable benefits to customers through a far wider range of available products and services.

Both Control Techniques’ and Leroy-Somer’s product ranges offer a complementary fit with the Nidec line-up, bringing significant benefits for all parties and, importantly, their respective customer bases. The combination will now allow Nidec to sell the entire range of products as a package into all key market spaces, while also allowing Control Techniques and Leroy-Somer access to new markets.

Nidec manufactures electric motors and related components, including small precision motors, motors for automotive, commercial and industrial applications, and medium voltage motors and generators. It employs around 140,000 people worldwide and has operations in over 40 countries. It has been actively developing a new growth platform with particular focus on appliance, industrial and commercial business.

Xavier Trenchant, President of Leroy-Somer said: “We are proud to integrate a business striving to become the world's No.1 comprehensive motor manufacturer and to join forces to meet the needs and expectations of our worldwide customers. With such a dynamic and trustworthy company, we look towards the future with confidence”

Scott Anderson, president of Control Techniques, said; “We believe this is a tremendous opportunity for us to join, work with and contribute to an industry-leading brand which believes in our products and will enable us to grow as businesses.”
