Driven by a clear industrial need for advanced inspection equipment for high-end permanent magnets for drives, sensors, medical applications, consumer electronics and other applications, we present a new magnetic measurement technology, called a ‘magnetic field camera’, a powerful and unique measurement platform for fast and accurate live inspection of both uniaxial and multipole permanent magnets. It is based on high resolution - high speed 2D mapping of the magnetic field distribution, using a patented semiconductor chip with an integrated 2D array of over 16000 microscopic Hall sensors. The measured magnetic field maps are analyzed by powerful data analysis software which uses advanced algorithms to extract unprecedented magnet information from the MagCam measurements. All these quantitative magnet properties can be tested against user-defined quality tolerances for immediate and automated pass/fail or classification analyses, all in real time. The system can be remotely operated using standard industrial communication protocols for integration in production lines. Its applications include inspection of incoming magnets, automated inline magnet quality control and research and development of magnets and magnetic systems and more.

Besides the latest advances regarding the integration of electric drives in automobiles, either as hybrid or full electric cars, the benefits of electric propulsion solutions are also highly interesting for commercial vehicles. A small size, a high protection class, low fuel consumption and a safe operation are basic requirements, which have to be met in order to design successful solutions. A complete drive system, consisting of a highly efficient permanent magnet synchronous machine with integrated inverter and an effective cooling system, safety- and energy storage devices, was developed in order to fulfill these demands. It is a very compact propulsion system, which could be easily integrated into different existing vehicle concepts. It is already implemented in vehicles and operated in continuous field tests in the full speed and power range. The system proved its effectiveness even in extreme temperature conditions.

The paper presents a simulation method, which helps to optimize the rotor design in terms of vibration and production costs. The method is particularly suitable for rotors that run close below or above the first bending critical speed, because a single-sided rotor core eccentricity excites this first bending mode very strongly. This simulation method can be used to optimize the rotor design to avoid elastic balancing. Rigid balancing can be used, even if the rotor runs above the first critical bending speed. Additionally, this method helps to find the tolerable residual unbalance and maximum tolerable limit for a single-sided rotor core eccentricity. Therefore the method helps to optimize the production process by avoiding elastic balancing and machining of the rotor core outer diameter.

Highly utilized permanent magnet synchronous machines (PMSMs) often show a significant inductance variation near and above the rated current values due to saturation. For precise modeling and control, the change in the parameters has to be considered by means of look-up tables. To parameterize these look-up tables, the inductances and the stator resistance have to be identified for various current set points. However, iron losses interfere with a precise identification if they are not considered. Therefore, an extended model is introduced to derive an identification method that considers and compensates for these effects. Measurement results prove the effectiveness of the proposed method.

Recent developments regarding the design of electric motors have set new requirements on the corresponding production processes. On the one hand, the manufacture of complex new bobbin geometries requires innovative winding technologies. On the other hand, the increasing number of permanent excited motors has to be taken into account through the development of highly efficient automation processes for magnet assembly. This paper presents alternative approaches for the automation of difficult assembly processes regarding these issues developed at the Institute for Manufacturing Automation and Production Systems (FAPS) at the University of Erlangen-Nuremberg.

This paper presents a technique to combine high currents and microelectronic control in a single system for power train and power supply applications. The combination is achieved by incorporation of busbars and other massive copper bars into a printed circuit board (PCB) to obtain high current load capability as well as heat sink for components with considerable power dissipation. Typical applications of automotive industry or avionics handle currents in the order of up to 1000 Ampere.

The induction assisted permanent magnet synchronous motor (IAPMSM) is a prospective choice for the electric and hybrid electric vehicle (EV/ HEV) drivetrain due to its lower losses, high efficiency and constant torque over a defined frequency range. This manuscript presents a part of an ongoing research project which is motivated towards building a prototype of an industrial 7.5 hp IAPMSM. Firstly, a new analytical approach to model the IAMPSM using rotor reference frame theory is proposed. The developed 7.5 hp IAPMSM model is then analyzed through calculated results and compared with the conventional model of the aluminum-rotor induction machine (ARIM) to elicit merits and demerits of the prototype being built. This paper aims to provide a comprehensive understanding of both the machines to serve as a guideline towards prototype development.

DYNAX® is a permanent magnet motor with a claw pole stator and axial orientated windings. Its external glass-fiber rotor with thin permanent magnets - a back iron is not necessary - provides a notable high torque and allows extended motor speed. Because of a considerable stray inductance and a low short circuit current, a quasi field weakening operation over a wide range of speed is possible. On the other hand, control and inverter have to manage high fundamental frequencies because of the typically high number of pole pairs. The presented paper shows the advantages especially for electric cars and starter alternators as well as the special demands on the electric motor control.

The development of low-noise motors will help to protect the environment and result in a competitive advantage. Designing low-noise electric motors means that it is necessary to predict the noise characteristics of the electric motor in the early conceptual phase. Customizing means that it is necessary to be able to estimate how the modifications affect the noise behavior of the motor. This paper presents two methods to calculate the electromagnetically excited noise of an electric motor, a numerical method for a more accurate result in the design process, and an analytical method for fast estimation in the customizing process.
