Almost every moving device is powered by an electro mechanical system. These systems are present in most electric motors, solenoids and mechatronics. From vehicle power windows and power seats to washers and dryers, many of the products we use in our everyday lives rely on these systems.
In this installment of the "Practicing Technician" series we will review the calculation required to determine the resistance of a given conductor. This often overlooked parameter can be important when trying to determine the appropriate wire diameter for a given application. It is also important to consider conductor resistance when examining application efficiency. Lower resistance means lower power dissipation by the conductor.
Two commonly misunderstood types of training are certificates and certifications. Both provide important value, but are quite different in terms of purpose, content, oversight and commitment required to complete them. Selecting the right training will ultimately increase your hire ability and/or value to your employer.
Most people use HMIs regularly in everyday life. For instance, when they’re adjusting the temperature controls in their vehicles or homes, they’re engaging a human-machine interface. In industrial applications, HMIs are often more complex interfaces capable of handling the volume and complexity of inputs and outputs necessary to operate industrial machinery or plant-wide operations.
In this installment of our "Practicing Technician" series, we will once again be working with a circuit reduction technique. This particular technique is quite useful for determining how changes in load conditions can impact on circuit performance. Until now, we have provided reduction techniques that are useful for fixed load circuit analysis. Thevenin's theorem can be used in cases where we want to see how load voltage, current and power are effected by changes in load resistance.
In the fourth part of our series on Tips For Practicing Technicians, we look at a simple technique that can be used to simplify circuit analysis when working with series and parallel RL circuits. One of the issues encountered by technicians who are working with parallel RL circuits is the need to work with values that are the reciprocals of the more commonly used standard units.
Augmented reality (AR) and virtual reality (VR) are two of the ways tech changes the way we look at the world. Whereas AR enhances our experience by superimposing digital images on our reality (think Pokémon Go), VR creates a completely different reality with a simulated environment. While both are typically used in technology for entertainment, they can also help improve industries such as manufacturing.
This is the third in our series of brief articles discussing important topics relevant to electronics and electromechanical technicians and technician students preparing for today’s workforce. In this series, we will be discussing some everyday skills and topics for practicing technicians, as well as some areas that have been identified as “difficult to understand” by our technician students while performing general circuit analysis.
Everybody knows that increased automation on the factory floor dealt a severe blow to manufacturing workers everywhere. Now, white collar jobs are also about to undergo quite a few shakeups as automation begins to take over offices, schools, hospitals and research labs everywhere.
Electromechanical switches are devices designed and used as additions for electrical circuits. They register over current, over-voltage, reverse power flow, and frequency. All of this is done in order to reduce the risk of major accidents or flashovers related to the electrical system within a structure or in machinery. Essentially, they work by tripping the circuit breaker when a fault is detected.
It's been a rough few years for the manufacturing industries, highlighted by the end of the first decade in the twenty first century where the most serious recession since the Great Depression affected most, if not all of the world’s economy. Most sectors seem to have rebounded, and the manufacturing industry is no exception.
The face of aviation is expected to change drastically over the next several decades. New regulations are driving the demand for electric and hybrid aircraft that produce fewer carbon emissions. Organizations like NASA and Airbus are leading the way to cleaner aviation by researching and designing green aircraft propulsion technologies.
The surprise result of the recent US election has highlighted the loss of manufacturing jobs like never before. Voters punished the status quo at the ballot box, at least partially because of their anger and powerlessness at big business outsourcing work to foreign countries. But the problem on the horizon is not so much outsourcing, downsizing, or imports as it is a fourth industrial revolution: the mass introduction of automation, which will replace low-wage workers with robots.
A recent technological breakthrough in the efficiency of the electric motor could mean that the average family’s grocery bill is about to drop – significantly. QM Power, a technology firm located in Kansas City, Missouri, recently broke the news to the world that it had developed an electric motor that promised to be at least 80% more efficient than Tesla’s (the man, not the automaker) induction electric motor.
One of the more remarkable consumer technologies to really take flight in the last few years are drones; but the one that is really turning heads is Parrot’s Oculus Rift compatible drone, Bebop.
