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.

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.

AB Elektronik expands market share for electronic hand throttles in India.

Werne – Manesar, May 2019 – AB Elektronik GmbH in Werne and AVX Electronics in Manesar have cooperated closely to expand their market share for electronic hand throttles in India. Their electronic solution for hand throttles has been adopted by leading Indian three-wheeler manufacturers, based on the system that has already proved successful in Europe.

The handle layout will be adapted to customer-specific local requirements, and production in Manesar will be expanded. “Our customers were especially impressed by our robust and advanced design, short development time, and the local serial production in Manesar, India”, says Praveen Gupta, General Manager – India.

In addition to local production the time factor is very important, because the Indian market for internal combustion engine powered vehicles demands innovative solutions for two and three-wheelers very shortly. The BS6 emission standards, which can only be achieved by the consistent introduction of innovative sensors in all vehicles in the country, will apply as soon as April 1, 2020. For achieving these standards, most OEMs will need to start producing their new engines by December 2019. Rapid development of this technology for the Indian market has been made possible by AB Elektronik’s know-how, and its many years’ experience in the integration and conversion of mechanical to electronic systems.

Electronic hand throttles work similarly to accelerator pedals in passenger cars. In this case, mechanical modules with Bowden cables are largely dispensed with. Controlling the powertrain with an electronic solution is much more precise, and therefore invaluable in meeting the proposed exhaust emission standards as well as provide additional features like signals for regenerative braking in E-bikes.

The AVX throttles work with non-contact sensor technology, with the sensor designed as a two channel system for the driver’s safety. The two sensor channels are independent of each other, and the sensor generates two independent signals proportional to the angular position of the throttle grip to provide redundancy. The electronic hand throttle is a key interface between the vehicle and the driver. The driver’s intentions are safely converted by the clear detection of the throttle angular position, and the corresponding signal from the throttle to the engine control unit.

AVX India expects further growth in this area through cooperation with a leading local manufacturer of cars, trucks, 3-wheelers, 2-wheelers and scooters. The latest E-scooters will in future be equipped with AB Elektronik/ AVX-branded electronic hand throttles for the Indian and European markets.
