Hairpin Motor Production Technologies
Alexander Kuehl, Research Director Electormechanical Engineering, Friedrich-Alexander-University Erlangen-Nuremberg (FAU)
The electrification of the drive train of passenger cars is currently undergoing an evolution from windings previously drawn in, which are known from industrially used electrical machines, to windings specially tailored to the requirements of mobile electric traction. A main trend is the use of pluggable shape windings, so-called hairpins. In order to fully exploit the economic advantages of this winding, elaborated production concepts and strategies are required. Due to the novelty and the currently ongoing innovation of these type of windings, the differentiated manufacturing possibilities per process step have not yet been fully defined. In view of the economic efficiency, high process speeds with increasing process reliability play a major role. The aim of this presentation is to show a process chain of hairpin technology that is as universally valid as possible, to name the different alternatives for each process step and to explain their characteristics.
Inverter Built-In Motor and System Diagnosis Reduces Field Returns and Creates Market Value
Cristian Ionescu-Catrina, Senior Marketing Manager, Power Integrations
We are analyzing the benefits of integrating smart diagnosis in the motor driver stage rather than adding extra components (sensors) and processing power. This reduces number of field returns and creates more market value. Particularly monitoring and reporting of following faults will be addressed in the presentation: over-current, over-temperature, over and under-voltage and motor vibration detection with minimum external components and microprocessor interaction. Lack of fault diagnosis or misdiagnosis of the motor and motor drive operation increases field returns. Relative high share (30 percent) of compressor returns come with no-fault-found that leads to unnecessary returns, inefficient resource allocation and unhappy customers. Ability to diagnose operation, take action and log faults in real time reduce the number of returns and service cost.
Effects of Deteriorated Magnetic Properties of Stators on Performance of Electric Motors
Lukasz Mierczak, Ph.D, R&D Engineer, Dr. Brockhaus Messtechnik GmbH & Co.
Accurate design and prediction of electric motor performance is not a trivial task. Motor design engineers make use of advanced numerical and analytical methods for electromagnetic and thermal analysis, and still find considerable differences in efficiency of modelled and manufactured machines. One of the primary sources for this mismatch is the inaccuracy in stator lamination magnetic properties, such as BH curve and power loss, which are used as input data for calculating flux linkages of the coils and heat dissipation, and consequently determining the main motor parameters including torque and operating temperature. In this presentation the results from Brockhaus case studies on the detrimental impact of manufacturing processes on magnetic properties of stators will be presented. Moreover, the effect of deteriorated magnetic properties of stators on final performance of electric motors will be analyzed.
A Historical Overview and Current Trends on Magnets, Electric Machines, and Drives
Dal Ohm, Ph.D., President, Drivetech, Inc.
Ever since Magnetism was first discovered by a shepherd named Magnes in Greece, applications of magnetic properties were slowly spread and evolved world-wide. With the invention of battery and discoveries on electricity and magnetic field, various types of electric motors/generators were invented during 1800s-1900s, and used for electrical power systems and high-power motors. After development of power semiconductors and electronic circuit, motor-generator control and drive technology has been advanced to high efficiency and precise control. This presentation will summarize past historical events and current technologies, then discuss on near-future advancement and applications of motor-generators with drives.
VFD Cable, Essential or Overkill
Steve Wetzel, Principal Engineer, Southwire Company
Variable frequency drive (VFD) systems can have issues with both radiated and non-radiated electromagnetic interference (EMI) which decreases system productivity. If EMI is left uncontrolled; motors, drives and other electrical devices in the facility may have operational issues or even be damaged. We will explore how VFD cable can mitigate many of these issues. We will identify three critical components to a VFD cable and explore how each component works to control the adverse effects of the drives high frequency pulse width modulated waveforms.
Operating Electro-Magnets with Current or Voltage Control Algorithms from Standard Industrial Drives
Carl Lee Tolbert, Vice President of Engineering, B&D Industrial
With the popularity of thyristor-based industrial DC drives being used in plants for extruders, winders, and other applications, does it not make sense to utilize the same drive without special firmware modifications also to run other applications? These alternative applications include lifting magnets, magnetic chucks, and magnetic separators. From a maintenance perspective, standard firmware equates to lest investment in training and spare parts inventory. To answer this, B&D has built custom electro-magnets, a test stand, and acquired an off-the-shelf thyristor-based DC drive to test two specific operational modes. The first operating mode test uses a single magnet with the DC drive in current control mode. The second running test uses two magnets in series with the DC drive in voltage control mode. The presentation will review the testing, findings, as well as a call to future research.

Experimental Approach for Solving Side Band Noise of Miniature Planetary Gearbox
Pradeep Deshmane, Principal Engineer – Gearbox, Portescap India Pvt. Ltd.
Vibration and noise spectra from miniature planetary transmissions commonly exhibit components at distinct frequencies around the gear mesh (tooth passing) frequency and its higher harmonics, called modulation sidebands. They constitute a significant portion of the vibration and noise generated by the transmission. Sidebands have influence on noise quality measures as well as having great potential to provide valuable clues regarding gear tooth combinations, phasing of planets, manufacturing errors like eccentricity, run out present in the gear set, planet pin position error, etc. The first critical step in designing and controlling the sideband activity of a planetary transmission is to develop a compressive approach to analyze modulation sidebands as well as describing the mechanisms causing sidebands. This session describes the investigation of side bands, correlation with test results and solution to minimize the noise. Practical examples will be provided. Benefits for a variety of aerospace and commercial applications will be highlighted to conclude the discussion.
Fast Magnetic Angle Sensor For High-End Robot Control Applications
Dr. Dragana Popovic Renella, SENIS AG Switzerland
Lennart Nachtigall, Robotics Systems Lab, ETH Switzerland
A Fast Magnetic Angle Sensor has been successfully applied in high-end robot control applications to precisely measure angle for very high resolution and accurate position control of fast robot actuators. At the Robotics Systems Lab, ETH Switzerland, various self-developed motor drives for robot arms and walking robots are developed. In these applications, the FAMAS absolute angle sensor can satisfy some requirements, which could not be reached with previously applied magnet-based absolute encoders. The requirements for use in the motor drive robot applications are: 10kHz update rate; a high magnetic resolution, i.e. a low-noise measured value (this requirement could not be satisfied with previously applied magnet-based absolute encoders); a high tolerance to electromagnetic interference for use in a motor; robust to allow using lower cost structural parts. The patented algorithm implemented in this sensor includes an innovative servo loop control system. It allows angle sensing at practically unlimited rotary speeds, with extremely low latency independent of angle. This sensor provides the digital value of the angle without additional hardware, significantly reducing total implementation cost.
