NYOMAG Neodymium line: quality for synchronous alternators with permanent magnet
Rd Europe Group has recently collaborated to the design of a permanent magnet alternator for welder for a new synchronous evolved alternator planned to be on the market in 2017.
It was required a more powerful magnetic rotor to increase the alternator power output. Our work focused on the identification of the quality of the best magnet for this project, with a meticulous testing we’ve identified NM40UH as the perfect solution for this specific project. We took a clue from the automotive sector in order to project a rotor with neodymium permanent magnets arc shape, so to meet the needs of encumbrance of the machine, ensuring a more flat object and therefore more compact than the previous one, however, able to ensure higher torque.
In just four weeks, RD Europe Group has designed and produced the perfect solution for the customer.
The product will be on the market in 2017 with 10,000 units.

CUSTOMIZED MAGNET FOR ELECTRIC MOTOR: DESIGN AND PRODUCTION OF MAGNET IN 4 WEEKS
A small Italian company manufacturer of small electric vehicles with battery (golf cars, handling equipment etc.) contacted RD Europe Group to develop the magnetic part of the electric motor for a new line of machines for the market. In the first place he needed a minimum quantity and secondly the production times were very tight. The RD Europe Group team immediately made the neodymium magnet as per client's project, producing a magnet perfectly in line with the demands. The result is a neodymium sintered magnet arc 45UH outer radius of 29.3 mm, inner radius 23.2, long 40 mm and 52 mm chord. Produced in just 4 weeks.
Our client was thus able to maintain production without having to block sales. A mission impossible that RD Europe Group made possible.

Plasto-neodymium alternator: superior quality for generator with magnet
In cooperation with a company, manufacturer of industrial generator, RD EUROPE GROUP has realized an evolved permanent magnet of superior quality capable to satisfy all customer needs. Final customer had different request, and did not find, on the market, any solution suitable for his wished performances. RD Europe Group team, starting from those needs, has developed a customized magnetic part that has become the magnetic heart of the motor of this evolved industrial generator. The magnet, a ring that emit a sinusoidal wave, has a diameter of 76 mm and a length of 100 mm. It is assembled on a 50 mm isotropic plasto-neodymium rotor, grade BM17D, that grant a residual induction of 900 mT. Thanks to RD Europe Group a firm has found the solution to make his product more powerful, safer and evolved compared with reference market. Discover what RD Europe Group can do for your company.
The advanced electric drill chooses brushless magnetic rotor
For a big German company RD Europe has proposed and produced a magnetic rotor technology that has improved the brushless motor of the new electric drill becoming so an innovative product. The magnetic rotor represents an important evolution in the sector thanks to the absence of brushes (brushless rotor): the magnetic rotor is then more compact and light than a conventional rotor, a fundamental characteristic of tools such as drills and professional powertool. The absence of brushes is also crucial to improve the longevity of the machine that doesn’t need maintenance anymore: the brushes and the commutator are in fact the most subject to usury. The brushless rotor requires less maintenance so provides a huge advantage for the end user. The magnetic rotor in neodymium finally ensures better power output in watts and a longer life of the battery about 30% for the same power. Specifically, the project for the drill involved RD Europe for the implementation of a rotor diameter 35 mm and length of 50 mm on which is mounted a plasto-neodymium ring with 8 sinusoidal poles and Br> 900 mT. The drill with magnetic heart is now on the market and it is significantly lighter, durable and high performance of the previous version.

The dynamo for bicycles that charges the smartphone: the new RD Europe project
A great challenge for RD Europe has been commissioned by a big Austrian company producing evolved bikes. The request was to improve the dynamo of the bicycle to be lighter and able to generate more power to charge many different types of devices connected to the bike through usb. The dynamo developed by RD Europe Group is also suitable for LED lamps and generates energy from 40 lux. It is also able to charge many different devices useful for who is riding the vehicle, such as mobile phones, smartphones, GPS etc. The dynamo weighs just 52 grams (becoming 90 gr with the support) and develops 6 times 1.5 watts at 8 km/H. At 30 km/h reaches 75% of the power. The developed dynamo is one of the smallest on the market nowadays and ensures a high efficiency for size and performance, a characteristic very appreciated by the end user. Find out how give a competitive advantage to your company products through innovation made in RD Europe Group.
Plastoneodymium ring: the power steering for racing car has a magnetic core
RD Europe produces, upon request of a racing car customer, a magnetic ring for EPS motor that improves the quality of power steering in terms of fluidity (cogging) and torch ripple. More accurate than conventional EPS engines, the engine made with the RD Europe ring improves ripple and torque, providing a smoother ride, which is crucial for car racing industry. The ring, made in plastoneodymium to reduce production costs, is a 20 poles Halbach and is very innovative for the automotive market. Thanks to RD Europe, the engine produced by our customer is now less expensive, more efficient and ensures a pleasant and a better driving accuracy.

A succesful history: The case Ambrogio
It was 2011 when RD Europe have been contacted to develop a new super compact powerful magnetic rotor for an automatic lawnmower robot: Ambrogio.
The new product was still in project phase and occurred develop a cheap system to launch on market this innovative product. The requires? Maximum level of compactness to reach a better last of robot internal battery, comparing with existing products. RD Europe so projected a rotor composed by shaft and magnet already assembled to realize the magnetic rotor. 4 plasto-neodymium rings of very little dimensions (15 mm high, diameter 25 mm, thickness 3 mm) glued together to create a sole magnet ring of 60 mm length. An extraordinary rotor for compactness, with the same power! Today, the new Ambrogio is sold in over 20.000 pieces per year, and continues to grant elevated performance also thanks to R&S dept. of RD Europe Group.
HOW TO PASS TO THE CLASS A +++ WITH THE MAGNET
RD EUROPE Group is responsible for developing assemblies and magnetic parts for various customers. Together with them we are able to redesign the product to save on production costs and improve the efficiency of the engine thanks to the use of the magnets. It’s the case of a magnetic ring designed for a world leader in fans and motors for cooker hoods: we have realized the piece to be compatible with the existing dimensions, so as not change the production but improve the engine’s yield, reaching the efficiency class A+++. The ring 4 poles realized by RD EUROPE is easy to assemble on the rotor and is modulated: the single module measures 20 mm and, depending on the power of the engine, it can be assembled differently. It is a considerable saving for production and assembly. The motor thus realized respects the American market UL/CSA standards. RD EUROPE Group designs and manufactures magnetic elements to improve your engine performance thanks to magnetic technology:
Fan coil more efficient and quite. Thanks to the magnet!
Today is always more important manufacture products in higher efficiency class, to optimize the use of energy in private and industrial environments.
That is why RD Europe develops for its customers assemblies with magnetic technology or customized magnets to improve product’s performance.
As done for Fan Coil motor technology, developed starting from a customer’s necessity, has brought the home appliance up to A+++ class rate. RD Europe has projected, together with end customer, the magnetic motor prototype, successively has produced a multipole neodymium ring magnet – realized in 3 different types for 3 different motor speed – improving the efficiency. With traditional technology… the result would not be possible! The magnetic ring is epoxy coated to protect from corruption, and grant more security and long last.
Magnetic technology can improve performance of your products.
