Power Integrations has added a 400W motor driver to its BridgeSwitch range of half-bridge power chips.

Power Integrations has added a 400W motor driver to its BridgeSwitch range of half-bridge power chips. Including high- and low-side fredfets (fast recovery diode field effect transistors) and ‘lossless’ current sensing, inverter efficiency of up to 99.2% is possible in brushless dc (BLDC) motor-drive applications, according to the firm. BRD1167 and BRD1267 deliver up to 1.33Arms (340V bus, trapezoidal commutation, 12kHz high-side PWM, 50°C case rise) and 11.5Adc peak (25°C case, 125°C junction). The difference between the two is that BRD1267 outputs a voltage proportional to low-side current, while the other does not. The chips are self-powered (supporting PWM commutation up to 20kHz) and come in a InSOP-24C surface-mount package. “These devices can drive single or multi-phase high-voltage, synchronous or asynchronous motors, and support all popular MCU and motor control algorithms,” according to the firm. “All BridgeSwitch ICs feature cycle-by-cycle hardware-based over-current, over-voltage, under-voltage and over-temperature protection” – simplifying IEC 60335 and 60730. A single-wire preventive maintenance interface enables communication between the host MCU and up to three ...

Lightweight scooter face off! Which is the best (light) electric scooter?

Don’t get me wrong, I love big and powerful electric scooters. But I don’t really want to carry a 95 lb (43 kg) electric scooter onto the subway or the bus. That’s where lightweight electric scooters come in. Today we’re going to have a good old-fashioned face-off between some of the most popular lightweight electric scooters under 30 lb (13.6 kg) to see which one could be right for your commute. For today’s comparison, we’re taking three of the most popular lightweight electric scooters we’ve reviewed, based on the response from our readers and viewers. Those three scooters are the E-Twow GT from eWheels, the GoTrax Xr Ultra, and the Unagi Model One E500. So now it’s time to see how they stack up against each other in the most important areas that commuters care about. And since seeing is believing (or for those that don’t enjoy reading, yet have made it this far), be sure to check out our short video below where the compare the scooters head to head. We’ll compare these scooters in the categories of price, power, speed, range, comfort, and convenience. And as you’ll see, those prices correlate fairly well with the rest of the specs, especially the power and speed. The GoTrax X...

Paris-based Régie Autonome des Transports Parisiens (RATP) has signed a contract with Solaris Bus & Coach

Paris-based Régie Autonome des Transports Parisiens (RATP) has signed a contract with Solaris Bus & Coach for the supply of the Solaris Urbino 8.9 LE 8.9-meter electric bus to Paris. Under the contract option, the public transport operator reserved the option to extend the contract to a value of €10 million. This means a possibility of delivering a further dozen or so zero-emission Solaris buses. The Solaris Urbino 8.9 LE electric will be equipped with a 160 kW central electric motor. The energy needed to drive it will be stored in 160 kWh Solaris High Energy batteries. A plug-in connection, through which the bus will connect to an external stationary charger will be used to top up the energy. The vehicle will be able to carry more than 50 people at the same time and will feature a 1-2 door layout. For passengers with limited mobility and those traveling with prams, the second door will be fitted with an electric ramp to facilitate boarding the bus. The interior of the vehicle will also be equipped with air conditioning, passenger information system, video monitoring system as well as fire detection and extinguishing system. Both inside and on the external elements of the ve...

Sensing internal organ temperature with shining lights — ScienceDaily

A cheap, biocompatible white powder that luminesces when heated could be used for non-invasively monitoring the temperature of specific organs within the body. Tohoku University scientists conducted preliminary tests to demonstrate the applicability of this concept and published their findings in the journal Scientific Reports. Thermometers measure temperature at the body’s surface, but clinicians need to be able to monitor and manage core body temperatures in some critically ill patients, such as following head injuries or heart attacks. Until now, this is most often done by inserting a tiny tube into the heart and blood vessels. But scientists are looking for less invasive means to monitor temperature from within the body. Applied physicist Takumi Fujiwara of Tohoku University and colleagues in Japan investigated the potential of a white powder called zirconia for this purpose. Zirconia is a synthetic powder that is easily accessible, chemically stable, and non-toxic. When heated, its crystals become excited, releasing electrons. These electrons then recombine with ‘holes’ in the crystal molecular structure, a process that causes the crystals to emit light, ...

10 Best Nano Drones: Micro Quadcopter and Small Drone Reviews

Consumer drones come in all shapes and sizes. At one end there are the big and heavy crafts. At the other extreme, you have micro drones that are so small you’ll miss them if you blink. Why would anyone want to bother with a little nano drone in the first place? Well, we’ve all got to learn to walk before we can run, or in this case—fly. These drones are perfect for kids and learner pilots. Not only that, but they’re affordable, durable, and safe for indoor flying. This guide looks at 10 of the best nano drones (aka micro drones) and mini drones at the present time. This can get confusing. Some makers call their mini crafts nano or micro drones. There are others who refer to their nano drones as mini in the product’s name. Fortunately, there’s a simple clarification. The difference between these toy drones is size. A nano drone fits easily into the palm of an average hand. Mini drones are about the same size of an average hand, give or take a couple of centimeters. Keep reading if you’re new to consumer drones or just want something safe for the kids to enjoy. Despite their tiny size, nano and mini drones are great fun and good entry-level crafts. Seriously, they’re super easy t...

Turquoise Hill announces financial results and review of operations for 2019

MONTREAL , March 21, 2020 /PRNewswire/ – Turquoise Hill Resources today announced its financial results for the year ended December 31, 2019 . All figures are in U.S. dollars unless otherwise stated. “For 2019, the Oyu Tolgoi mine recorded another year of excellent operational results, and record industry-leading safety performance,” stated Ulf Quellmann, Turquoise Hill’s Chief Executive Officer. “Our team at Oyu Tolgoi continues to maximize our production efficiencies, which resulted in our full year copper production to fall within our original guidance, and our gold production exceeding our original targets. In addition, the mill throughput achieved its fourth year in a row of operating at above name-plate capacity.” “2019 was also a pivotal year for the underground development with the completion of the above-ground infrastructure and Shaft 2. Shaft 2 is a critical piece of infrastructure that allows the team to accelerate the underground development. Productivity gains in the underground development over the last five months of 2019 have shown steady improvements with December achieving a new record of over 1,800 meters of lateral e...

Best of 2018: Strategies for orthopedic component processing

Five major suppliers claim approximately 85% of the highly competitive orthopedic device and implant market, with more than 200 other companies vying for the remainder. In light of such intense competition, recent developments allow medical manufacturers to continually seek ways to machine components faster and more cost efficiently. Some of these innovations and strategies include dry coolant and 3D printing, along with advanced cutting tools and high-speed milling. Orthopedic components are typically machined from bar stock, castings, or forgings, then ground and polished. For hip and knee implants, the most common workpiece material is titanium, with the use of cobalt-chrome alloy increasing. A typical cobalt chrome alloy is similar to CoCr28Mo6, and the titanium alloy Ti6Al4V is most common. The JH770 end mill is engineered for roughing operations and is available in 4-, 5-, and 6-flute styles, enabling variations of the tool to rough from solid or perform near-net-shape operations. Because the materials used in orthopedic implants typically generate excessive heat when machined, coolant use is required. However, using traditional coolants is often prohibited or limited to p...
