Participate our Webinar: “SPINpad Sensors Outperform VR Resolvers in Terms of Economy, Functionality, & Flexibility in Hybrid/Electric Powertrains”

On Wednesday, May 27, 1 pm EST Matthias Knoche, Product Application Manager Speed Sensors will give a live webinar about our innovative SPINpad technology.



The functionality and effectiveness of electric motors and driver assistance systems is critically dependent on the reliability of the sensors that convert physical variables, such as speed or position, into electrical signals and transmit them to the control unit. One of the most crucial sensors in electrified powertrains — the rotor position sensor— is located within an electric motor, which is an exceptionally challenging environment. VR resolvers are the current standard technology solution but have no active electronics, which means that they can’t offer any self-diagnostic functions, and are costly considering the technology principle and manufacturing processes.

AB Elektronik developed SPINpad Rotor Positions Sensors to provide hybrid/electric powertrains with more economical, functional, and flexible alternatives to VR resolvers. SPINpad sensors incorporate active electronics, which allows them to support redundant systems designs that meet stringent safety-critical applications requirements per ISO 26262 functional safety guidelines, solve accuracy issues common to VR resolvers, reach maximum speeds of up to 100,000rpm depending on the number of pole pairs within electric motors, and provide digital or analog output signals with readiness for ISO26262 up to ASIL C with one channel or ASIL D with a redundant system. SPINpad sensors are also more flexible in terms of assembly, featuring a very thin form factor with high magnetic immunity and various assembly options for substrates ranging from PCBs to fully metallic targets.

AB Elektronik Sachsen GmbH: Georg Schafrath says goodbye and takes over the management of Salzburg on April 1st

A farewell that will become official on 1 April 2020. On this date Georg Schafrath will take over the role of Managing Director of AB Mikroelektronik in Salzburg, also part of AVX Sensing and Control Division. AB Elektronik Sachsen GmbH will be managed on an interim basis by the long-standing plant management team members Aldo Bojarski, Head of Development at the Klingenberg site, and Lars Warnecke, Head of Finance of the Sensing and Control Division.

Originally planned in the context of a works meeting, the farewell took place on a much smaller scale than planned, in the spirit of social isolation. However, Georg Schafrath found very personal words for the workforce and management team, who have backed him with unreserved loyalty since 2017. As a member of the Supervisory Board, he will continue to be associated with the plant in the future. 

Herr Schafrath takes up his new role with optimistic foresight. “AB Mikroelektronik stands for innovative automotive technologies with the Power Module and LED technologies product lines, strong application depth and customer specific developments. With worldwide production at the global locations of the AVX group, together with the local team we continue to build on our strengths.”

AB Elektronik: Rotor Position Sensor for Electric Motors

Inductive SPINpad Rotor Position Sensor from AB Elektronik optimizes the efficiency of electric motors

It’s a highly topical issue: alternative drive concepts and further reduced fleet emission limits (limit value 2020: 95g CO2/km) require solutions. Here, the electric motor is considered to be the alternative with the highest short term efficiency in powertrain optimization.

Designed-in solutions: the SPINpad sensor offers high immunity to interference, and cost advantages through a simplified design

Achieving high efficiency from an electric motor requires precise control, and the lower the specific energy consumption, the greater the range of the vehicle. A fundamental control variable for motor control in this context is the rotor position within the electric motor.

AB Elektronik’s rotor position sensor is a further evolution of AUTOPAD inductive technology – with many million products in the field.

The inductive system is characterized by an immunity to low frequency magnetic fields up to 150kHz. The circuit board based design of the coil structures, and the resonant operation, allow several sensor systems to be located in a very small space. These are designed to meet functional safety requirements (ISO 26262) up to a maximum level of ASIL D. Many years’ experience in inductive technology has enabled a simple product design, ideal for highly automated production. The associated cost advantages make the system more attractive than comparable solutions.

Made for the future: Forward thinking in the design of the rotor position sensor supports self-diagnostic functions, and paves the way for use in autonomous vehicles

This is novel in the field of rotor position sensors, as existing technologies (e.g. VR resolvers) are purely mechanical/passive sensors without self-diagnostic functions. This can lead to control software problems in the growth phase of autonomous driving, as such sensors cannot be adequately secured against potential errors.

Depending on the application requirements, the SPINpad sensor can be designed as a 360° system. Alternatively, to simplify installation and for large diameters, a circular segment design can be adopted. Depending on the design of the vehicle, the system can be mounted on the shaft (‘through-shaft’), or on the end of the shaft.

In combination with AB Elektronik’s innovative direct injection moulding technology, a SPINpad rotor position sensor is robust against even the most demanding requirements in the customer application – for example, continuous operation at 150°C in transmission oil.

AVX – Generic Coronavirus Statement

AVX website generic Coronavirus (COVID-19) alert

The spread of the coronavirus (COVID-19) in China these past few weeks has caused the World Health Organization to announce the situation as a Public Health Emergency of International Concern and for the Legal Work Committee of the National People’s Congress to declare that, unless otherwise provided by law, the current measures taken by the Chinese government to protect public health are force majeure events and shall excuse a party’s inability to perform part or all of its obligations.

Most airlines and many shippers have stopped their services to and from China either partially or fully. Further, many facilities in China are still closed or are on reduced production schedules.

Each province is responding to this emergency separately. In particular, AVX Group manufacturing facilities have been significantly affected. In addition, the supply of protective equipment such as masks, non-contact thermal measuring devices, and the like is disrupted and there are shortages both in China and elsewhere.

As a result, there has been a substantial impact on the supply chain of products either manufactured in China or which incorporate components that are manufactured in China.

The situation is very fluid with new announcements being made without any prior notice by governmental units, manufacturers and transporters.

These circumstances are unforeseeable and outside the reasonable control of the AVX Group and in the nature of “force majeure,” thereby creating impediments to members of the AVX Group in providing its products and services to its customers.

Accordingly, AVX Group shall be relieved of any liability under any contract for services to and from China if, and to the extent that, such liability is caused by the consequences of outbreak of coronavirus.

In view of the aforesaid force majeure situation, AVX Group reserves the right to modify all or part of its obligations to provide products services that are manufactured in China or which contain components manufactured in China, to change its working procedures, to charge surcharges or otherwise to take measures to adjust its business operations and obligations towards customers to the then prevailing circumstances arising as a consequence due to outbreak of coronavirus.

Global player for commercial-vehicle-applications

Robust technologies and global footprint 
The enormous diversity of transport requirements for commercial vehicles calls for a wide range of sensor solutions of the highest quality and robust design. Partnering with most of the Premium OEM in the truck market we can offer a comprehensive portfolio of customized solutions.

Exhaust gas after-treatment

Since the EURO 4 standard, AB Elektronik has been an accredited partner of truck manufacturers for development and production of sophisticated sensor solutions for exhaust gas applications.
To complement our existing technologies for exhaust gas monitoring we are on course to meet the requirements of Euro 6 and Tier 4i and f emissions.
The functional diversity of gas sensors from AB Elektronik now offers practical, economical and powerful complete solution from a single source.

For future applications, the nitrogen oxides (NO,NO2=NOx) generated in the engine during combustion have to be eliminated actively.
In the so-called selective catalytic reduction (SCR), an aqueous urea solution (32.5% NH3) is injected into the hot diesel exhaust.
The result is non-hazardous N2 and H2O. For requirements-based metering of the solution, exact detection of pressure and temperature is necessary.
For this pressure sensor, the AB experts selected a specially capsuled measuring cell which in a compressed-air-free system guarantees that there is no freezing, as this area in case of sub-zero temperatures is exposed to outside temperature due to mostly little insulation.
For optimum control of a number of additional functions in exhaust gas after-treatment, AB Elektronik possesses innovative products and a high overall expertise in this special field.

AB Elektronik develops standard concept for urea sensor

Since Euro standards have been regulating the pollutant emissions of modern engines and exhaust systems, automobile manufacturers and system partners have relied on sensors from AB Elektronik.
The measurement of urea quality is the third product column for exhaust gas sensor technology – alongside temperature and pressure measurement – with which the experts from Klingenberg, near Dresden, are finding success in global markets.

After consistent development of their optical urea concentration sensor, AB Elektronik has introduced standardization as a modular system, which opens up clear advantages over complex systems with ultrasonic units and other measuring methods. The optical measuring method allows a very compact sensor design, which proves to be extremely robust in demanding environmental conditions. The compactness allows for versatile use in different mounting systems, both in or at the urea tank, as well as in the supply line.

Frank Rothe, Product Manager for this product group, puts the increasing demand in the automotive sector down to the need for permanent measurement of the urea content in the fuel additive known as AdBlue. This is used to eliminate nitrogen oxides in diesel vehicles, and in modern automobiles, continuous measurement of its quality is now mandatory. If the concentration does not comply with the specifications, or if the level in the tank can no longer be measured, the driver receives various warnings until the vehicle finally switches to emergency mode. The sensor is also used for similar functions in tanks and industrial plants.

“We see a wide variety of requirements regarding the installation space, and the interfaces for measuring urea content”, says Mr Rothe. “Not every requirement can be supported with a completely new design if the required quantity is small. This has led to our development of a modular standard, which we will offer in the future with a partner, among other things as a complete tank sensor unit. As a competent partner in the field of exhaust gas sensor technology, we are convinced that this step will help our customers to optimize their systems.” Frank Rothe continues: “Development of the technology is in the hands of our European competence centre; production and local design adaptation takes place in our international locations.”

Battery switch from AB Mikroelektronik

AB Mikroelektronik battery switch enables fast, safe and noiseless disconnection with high-performance electric vehicle batteries.

E-mobility is changing the future of transport. This technology change is a global trend, and between 2020 and 2030 should become a reality for a broad base of consumers. For several years now, hybridization of vehicles has been rolling out across the fleets of many car manufacturers, and continued progress is expected.

AB Mikroelektronik´s innovative packaging technologies offer high performance for power semiconductor modules

One of the keystone technologies in this transition is the dynamic field of power electronics. Assembling and packaging power semiconductors in a highly efficient way, both for lowest power dissipation and highest heat conduction, provides the route to increased range, faster charging and many other advantages. AB Mikroelektronik has transformed these demanding requirements into an optimized packaging concept, and today offers customer-specific solutions for even the smallest installation spaces and the highest thermal requirements.

AB Mikroelektronik´s battery switch achieves high power density in a small package volume

Among these newly developed technologies is a powerful switch that disconnects the battery of an electric car from the power train in a fast, safe and noiseless way. Bare die semiconductors are directly attached to rigid aluminium metal substrates, produced using thick film technology. Both isolating and conductive electrical tracks can be applied in a flexible way on the substrates. The switch is located directly between the battery positive terminal and the load, and controls current flow in both directions.

All-aluminium power module for efficient and reliable connection to high current busbar systems

Parallel connection of multiple power semiconductors means higher currents can be supported, with power dissipation shared between them. Typical on-state resistance of the complete power module is as low as 0.75 mOhm at 25 °C. Very low thermal resistance of the module of only 0.2 K/W from semiconductor junction to water is achieved by applying materials with a high thermal conductivity. This property is mainly achieved by the pure aluminium metal substrate on which bare die semiconductors are directly attached. For transient current pulses, the thermal resistance is less than 0.1 K/W, which allows rapid power dissipation of about one kilowatt. For protection against humidity, and increased electrical isolation and ruggedness, the complete module is packaged in an epoxy compound with additional integrated sensors for temperature, voltage and current sensing.

The high efficiency of this module assures a cost effective design and minimum power consumption in typical e-mobility applications.
