FAQ on magnetos for power and ignition, Part 2
This simple, mechanically driven power source is nearly 200 years old and still has a well-defined, albeit limited, role in today’s systems. Most of the historical and present-day applications for magnetos are for spark-plug ignition systems. This part looks at that aspect in more detail. Q: What’s the structure and operation of a basic magneto-based […]
Why 3D packaging could be the next breakthrough for processing
As semiconductor manufacturers start to reach the potential physical limits of shrinking process nodes, chip packaging is emerging to improve performance. Flip chip assembly remains the most popular method for interconnecting dies, but new advancements in silicon interposers are enabling 2.5D packaging architectures and, in turn, making 3D packaging possible. To help you learn more […]
FAQ on magnetos for power and ignition, Part 1
This simple, mechanically driven power source is nearly 200 years old and still has a well-defined, albeit limited, role in today’s systems. What or who is a magneto? No, a “magneto” is not only the powerful mutant who has the ability to generate and control magnetic fields and first appeared in the debut issue of […]
How do I choose an electric motor, and how do I test it? Part 4
You indeed can measure three-phase power in a motor with just two wattmeters. Part 3 of this FAQ concluded with a simplified diagram showing a test setup that included a programmable power supply, a motor under test, a mechanical load, a power analyzer, and host computer. The programmable power supply could simulate the AC line […]
Why advanced packaging is vital to the future of semiconductors
The cost and the physics of fitting more transistors in the space available are showing diminishing returns. The concept of “known good die” is much more difficult to quantify. For all the talk in the semiconductor industry about trying to reach 1.8 nm process nodes, advanced packaging and its impact on performance seems to be […]
What is electric vehicle supply equipment (EVSE)?
EVSEs provide power to charge EV batteries at Level 1 and Level 2 voltage ratings. Electric vehicle (EV) owners rely on electric vehicle supply equipment (EVSE) to charge their batteries efficiently. Often referred to as charging stations or docks, EVSEs provide a reliable and safe connection between EVs, the electric grid, and other energy sources. […]
What is a lithium battery digital passport?
Introduction A digital battery passport provides easy access to structured, reliable, and complete information about the battery. This fresh initiative in the US lithium battery landscape aims to simplify consumers’ choice and use of batteries. The US government agencies are working on battery passport requirements, centralizing battery specifications and pertinent details, making it user-friendly for…
What advanced sensing techniques are used in cobots?
Most robots incorporate a broad range of sensing technologies to better understand the operating environment and to fulfill their design purpose. These sensors provide information about position, size, orientation, velocity, distance, temperature, weight, force, and more. For collaborative robots or cobots that operate in a close proximity to and even interact with humans, additional sensing […]
How do I choose an electric motor, and how do I test it? Part 3
Motors follow the path of less reluctance to rotate. Thus, you need timing of applied power to get them moving. Part 1 and Part 2 of this FAQ looked at brushed and brushless DC motors, permanent-magnet and wound-rotor synchronous motors, and induction motors. These motors all have drawbacks, including mechanical wear of commutators, slip rings […]
