Motion Control Application- maxon motors in the Formula Renault 3.5!
The Formula Renault racing series has become one of the most important racing series for future world-class Formula 1 drivers. Since 2012, a new, more powerful V8 engine has been roaring under the hood of the World Series racing cars. Inside it, maxon motors are responsible for adjusting the electronic throttle system.
 |
Fall River, MA — Motion Control Components Application – The World Series by Renault is a combination of several racing series. The main series is the Formula Renault 3.5. The prestigious Formula Renault 3.5 has become one of the most important racing series for future world-class Formula 1 drivers. In recent years, several drivers have succeeded in making the jump from the Formula Renault 3.5 to the Formula 1, such as Jean Eric Vergne and Daniel Ricciardo of the Scuderia Toro Rosso, as well as current world champion Sebastian Vettel from Germany
The Formula Renault 3.5 is considered to be a preparation series for the Formula 1 and therefore the vehicles have many of the characteristics of the top motorsport class: Carbon brakes, semi-automatic gearshift, left foot brake, and, since 2012, a powerful V8 engine and an adjustable rear wing. In the new World Series vehicles developed by Renault, Zytek engines are used. Zytek is a British company that produces control systems for the automotive industry, drive technology, engines and hybrid technology. All 26 vehicles used in the Formula Renault 3.5 are driven by the new Zytek engines. The engine has been designed especially for the Formula Renault series. The 3.4 liter V8 engine, with its 530 hp at 9250 rpm, provides 50 hp more than the previous engine. And where the weight is concerned, the new Renault again has the edge, as it is around 15 kg lighter than the previous model. A fly-by-wire throttle control system has been integrated into the engine. This system, also called “drive-by-wire” in motorsport, electronically transmits the gas pedal movements to the engine controller. In principle, it handles how far the throttle valves are opened at which pedal position.
This gives the racing driver the ability to obtain a specific torque from the engine at a certain gas pedal position and the respective engine speed. In the case of the Formula racing car, there are three different levels (pedal maps) for different route conditions.
Strong vibrations conquered easily
Accurate control of this throttle system is handled by a maxon DC motor and planetary gearhead. This technology makes the racing cars approx. four seconds faster per round. The maxon DC motors from the RE motor family and the gearhead from the GP family were specially adapted to meet the demands of the high vibration and high temperature environment. During the test phase, the maxon engineers – in close cooperation with Zytek – verified that the engines can function problem-free under the challenging loads. “We began testing maxon’s products in July 2011 and have been extremely impressed with their technical backup and service. The motors need to work in a very hostile environment and maxon really understood the product and the problem and even made suggestions on how to improve the product to help us,” said John Manchester, Operations Director at Zytek. Paul Williams, Sales Engineer at maxon motor uk, commented: “We are delighted to work in partnership with Zytek. 80% of our business comes from modifying our products for our customers and we thrive on challenging projects.”

Motion Control – Application Story – Sound of Light from Intellidrives!
Optoacoustic tomography (OAT) is a technique for generating high-resolution images of biological tissue that scatters light waves, typically biological tissue..
Image courtesy of Tomowave
Philadelphia, PA, — Motion Control Components and Systems – Application – OAT systems create these images with pulses of dark red light that have a maximum duration of 50 nanoseconds. These pulses heat the tissue and cause it to expand launching ultrasound wave, a phenomenon known scientifically as an optoacoustic effect. This thermo-elastic expansion produces high-frequency acoustic or ultrasonic waves that the imaging scanner detects and uses to create an image with computational methods such as filtered back-projection. OAT is unaffected by the scattering of photons, allowing it to take high-resolution images of deep biological tissue.
OAT also uses techniques such as functional and molecular imaging to identify each absorbing molecule that contributed to the image brightness. OAT uses light of different wavelengths to target various molecules of medical interest, such as hemoglobin, oxyhemoglobin and melanin.
This approach allows OAT to distinguish between molecules in the target tissue with different light absorbing properties, including exogenous contrast agents such as imaging probes to appear distinctly different on optoacoustic images.
Science at Work
Scientists at Tomowave Laboratories use technologies based on light and sound to make imaging systems for the healthcare industry. These technologies use optoacoustic and laser ultrasonic methods to produce modalities such as laser optoacoustic ultrasonic imaging system, which uses pulses of laser light with a dark red color.
Biological tissue absorbs this light, causing it to heat-up by a fraction of one degree. The resulting temperature increase causes an increase in pressure, which generates ultrasonic (optoacoustic) waves. The imaging scanner uses arrays of transducers to measure these ultrasound waves at different locations to generate images of internal tissue of different human and animal organs, such as breast or prostate. These systems listen to the sound of light, allowing doctors to detect and diagnose cancer and other conditions.

Recently, engineers at Tomowave have developed a system that combines light and sound to generate three-dimensional images of tissue submerged in the imaging module, primarily the tissue of small animals used for research purposes and development of new contrast agents or therapeutic methods.
This optoacoustic tomography system is the first of its kind to produce functional 3D images of biological tissue with equally high resolution in each volumetric direction. The system provides comprehensive information on anatomy and function. These images are especially useful for studying the distribution of blood and its oxygenation level.
Imaging Module
This system’s imaging module uses a 360-degree rotation to generate three-dimensional images.

IntelliDrive- PSR 180UT Ultra Thin Rotary Table
Preclinical research systems rotate the object of study, while the module itself rotates in systems used in clinical settings such as breast imaging systems.
Noninvasive breast imaging systems apply the same technology to produce three-dimensional volumetric optoacoustic images and stack of two-dimensional ultrasonic images, allowing for image co-registration.
These systems produce scans at different wavelengths in minutes with minimal patient discomfort.
Custom software processes the volumetric data according to the specific items of interest, which may include hemoglobin content, oxygen saturation and vasculature visualization.
The imaging system uses a PSR180UT low profile rotary servo table from IntelLiDrives to rotate the imaging module at a constant speed, which is programmed in advance.
A real time precision encoder output allows synchronization of the image capture with the motor’s position, allowing the system to reconstruct the images in three dimensions.
