Welcome to the February Analog Dialogue
The motor efficiency drop caused by motor faults or motor anomalies has drawn increasing attention since they can persist over long time periods and can lead to significant economic losses. In this month’s feature, “Improving the Efficiency and Sustainability of Electric Motors,” learn how common motor failures affect the efficiency of motor operation and how the ADI OtoSense™ Smart Motor Sensor (SMS), a predictive diagnostic maintenance solution, ensures that motors operate at high efficiency.
Power converters typically incorporate a control loop to maintain a set output voltage, irrespective of variations in input voltage or load current. The article “Regulation Loop Without a Resistive Divider” explains how a new control loop architecture is designed to generate very low noise voltages. In addition to the low noise achieved, the level of noise becomes independent of the set output voltage. This also makes it possible to generate very low output voltages down to 0 V.
The article “LED Driver for Industrial Power Supply Indication” is this month’s next feature. This article presents a simple and small solution for driving an LED to provide visual feedback in the presence/absence of a system’s power. The circuit consists of a resistor and a small chip, originally not intended for this purpose, which replaces a multitude of components in the conventional solution. Standalone and low power in nature, yet robust to miswiring, make it destined for industrial and similar systems.
As 10BASE-T1L Ethernet emerges across various industries, more applications come to light, each bringing new challenges to be addressed to successfully deploy the technology. A common requirement is to support a wide range of cable types. This month’s RAQ, “10BASE-T1L Single-Pair Ethernet Cable Reach and Link Performance,” summarizes the cable characteristics relevant to this technology, describes the dependency of cable reach as a function of these characteristics, and provides a list of cables that have been tested.
Dive into the world of Hartley oscillators with our latest StudentZone article, “StudentZone—ADALM2000 Activity: The Hartley Oscillator.” In this laboratory, we examine the Hartley configuration, which uses a tapped inductor divider to provide the feedback path.
And as we have for over 58 years, we invite you to be part of the dialogue in Analog Dialogue. You can get in touch through our blog, Facebook page, or email. Let us know how we’re doing and what you’d like to see from us in the coming months.
