A more fluid drive thanks to magnetic heart powersteering.Motors meet automotive
RD Europe Group has cooperated with a famous company, manufacturer of tractors, to improve drive experience of a vehicle thanks to magnetic power steering. Customer was trying to make more fluid the drive of a tractor model, to improve the drive experience of final user. In order to do that, RD Europe has redesigned the electric motor together with German University of Braunschweig. Has been projected a ferrite magnetic ring rotor, magnetized halbach 20 poles with Br>440 mT. In that way, thanks to the magnet, the power steering grants a more fluid and precise steer. Moreover, the new magnet studied by RD Europe Group is easier to be realized, granting an important saving in its realization. The magnetic solution studied by RD Europe for tractor power steering is inspired to solutions already used in automotive and lift truck field, but never applied to agricultural vehicle industry.

Halbach technology: for powerful motors
The European leader of home appliance has cooperated with RD Europe to improve their drain pump through the design and implementation of an innovative magnetic system. The customer requested a ferrite ring ,Halbach magnetized 6 poles, that could work under water, with speed up to 6000 RPM and resisting thermal shock from 5 to 80°C. The ring was designed by RD Europe team and implemented with a Wet Anisotropic magnet with induction> 400 mT. Thanks to this magnet, the motor of the appliance is quieter, more efficient and has a better energy class: a significantand competitive advantage in this marketplace! RD Europe is able to design and produce parts and assemblies with high-tech level, also for small and medium-sized companies, supplying customized items. Discover how is easy to innovate.
From Neodymium to ferrite magnet: the patent to bring down the cost of neodymium
A big German car manufacturer has asked us to develop a special ferrite ring magnet for electric motor. The request was simple but at the same time very ambitious: nowadays the piece is made by neodymium, a rare earth material of high magnetic quality but is hard to control its price on the market. RD Europe Group has therefore studied the magnetic properties, designing a solution to ensure a significant saving on the magnet. The choice fell on ferrite: we have developed a very small anisotropic ring (55 mm outside diameter, 35 mm inside, and a thickness of 20 mm) a 20 pole Hallbach Array: a very small and particular object, which ensures a minimum of 190 mT on the surface up to a maximum of 300 mT.
Mission accomplished! The ring will be launched on production in the coming months, in millions of pieces with significant savings for the manufacturer.

A small magnetic ring for a great revolution
RD Europe has designed an innovative magnetic system to improve the performance of the drain motor for washing machine. We started out by the target to achieve a more economical system than the existing ones, more powerful, and that maintained an A +++ energy rating. Exploiting the Halbach array layout, we have realized a rotor whose magnetic flux does not close on the bore, avoiding so a metal part closing the magnetic field, it’s a solution less expensive for the realization of the piece (today plastic injected) and so a less heavy motor. The magnet made of Anisotropic ferrite IMF7, is assembled directly on the shaft, homologated for 5,000 wash cycles and works smoothly in the presence of thermal shock due to cold and hot water.
