Higher Value Engineering than Resolvers! TMR Angle Sensors as Advanced Solution for E-Motor
As environmental awareness grows and the realization of a sustainable society becomes increasingly important, the mobility market is witnessing an active movement towards “EV adoption," aiming to transition from gasoline-powered to electric-powered motor vehicles. In order to realize higher performance electric vehicles (EVs) and electric motorcycle, next-generation electric motor technology that balances factors such as high efficiency, high reliability, compactness, light weight, and cost performance at a high level is required.
 
In this article, we make a comparison of angle sensor technologies responsible for detecting rotational angles in traction electric motor (hereafter referred to as e-motor) control and explain how our TMR angle sensors enhance your design.
TDK präsentiert Demokit für Ultraschallsensormodule zur Erkennung von Hindernissen
Die TDK Corporation präsentiert ein Demo-Kit (Bestellnummer: Z25000Z2910Z001Z21) für das mechanisch entkoppelte Ultraschallsensormodul USSM1.0 PLUS-FS (Bestellnummer: B59110W2111W032). Dieses Bauelement lässt sich einsetzen, um Hindernisse zu erkennen und Abstände in anspruchsvollen Umgebungsbedingungen zu messen, z. B. bei direkter Sonneneinstrahlung und transparenten Zielobjekten bei autonomen mobilen Robotern (AMR) oder autonomen fahrerlosen Transportsystemen (Autonomous Guided Vehicles, AGV).

Compact and low power consumption CO₂ gas sensor (Under Development)
Global warming is currently an issue of worldwide concern. CO₂ (carbon dioxide) not only contributes to this problem but also has a significant impact on our health. In the pursuit of improving air quality in various environments, such as homes, offices, and hospitals, there is an escalating demand for sensors capable of detecting CO₂ and various other gases. TDK is developing a CO₂ gas sensor that is significantly smaller in size than previous sensors and consumes less power.

Applications & Cases
Application Note
The Metaverse Will Engage All Five Senses
The technology that delivers the metaverse will build on the technology for virtual reality, using more sensors, and more different kinds of sensors. TDK has one of the richest sensor portfolios in the industry, extensive software expertise, and excels at sensor fusion.
Application Note
Failure Modes and Countermeasures in Actual Use of NTC Thermistors
NTC (Negative Temperature Coefficient) thermistors are thermally sensitive semiconductor resistors which show a decrease in resistance as temperature increases, and its rate of change is extremely large.

Its main applications include temperature sensing in electronic equipment and temperature compensation for module products.

However, if the user misuses the product, it may not function properly and, in the worst case, this may cause malfunctions.

This page introduces the causes and countermeasures for ”cracks” and ”melting of ceramics” as failure modes caused by improper use of NTC thermistors.
Sensors for New Mobility
【How electrification and autonomous driving are expanding the role of sensor technologies within automotive designs】

The automotive production landscape is changing. The proliferation of electronic devices and sensors in modern car design has grown exponentially in recent years. It will expand further as the industry continues its transition toward e-mobility and autonomous driving. The core technologies featured in electric vehicles expand the realm into which sensors are deployed. Also, combustion engine vehicle gas sensors have shifted away from exhaust gas monitoring toward internal air quality (IAQ) measurement.

    • TDK Produktbeschreibung
    TDKs komplettes Sensorprogramm, das unter den Produktmarken TDK, EPCOS, InvenSense und Micronas vertrieben wird, umfasst Temperatursensoren, Drucksensoren, Winkelsensoren und Stromsensoren. Präzise Stromsensoren sind für intelligentes Energiemanagement in Elektrofahrzeugen und Smart Grids unverzichtbar. Temperatursensoren und -sensorsysteme dienen beispielsweise zur Temperaturregelung von Kühl- und Klimaanlagen oder zur Messung der Temperatur von Betriebsflüssigkeiten in Kraftfahrzeugen. Drucksensoren werden in einer Vielzahl von Anwendungen in der Automobil- und Industrieelektronik, der Medizintechnik und der Umwelttechnik eingesetzt. Magnetfeldsensoren, die auf Hall-Sensor- oder TMR-Technologie basieren, sind in fast jeder Maschine zu finden, die Positions-, Linear-, Rotationsbewegungen oder sogar Strom messen muss. Bewegungssensoren erkennen und verfolgen die Bewegung eines Objekts im dreidimensionalen Raum und ermöglichen wichtige Funktionen in vielen Geräten der Unterhaltungselektronik. Anwendungensmöglichkeiten sind Mobiltelefone, Wearables, Smart Home-Produkte, sowie Automobile und Industrieanlagen. Für hohe Anforderungen in der Bewegungserfassung bietet TDK MEMS-Produkte an, beispielsweise Beschleunigungssensoren und Gyroskope für die Navigation, Bewegungsverfolgung und Bewegungssteuerung sowie die optische Stabilisierung.
