The influence factors on the energy-efficiency of electric motors, pumps and fans are put forward in this chapter. Suggestions to improve the energy-efficiency of electrical motor products are presented.doi:10.1533/9780857093813.139Jianfeng Yu
MPGe is the EPA equivalent measure of gasoline fuel efficiency for electric mode operation. 4. Wi-Fi hotspot includes complimentary wireless data trial that begins upon AT&T activation and expires at the end of 3 months or when 3GB of data is used, whichever comes first. To activate, go to...
Every battery you'll find on a Trek e-bike has a sophisticated battery management system (BMS), which is like a security guard for the battery's cells. It's constantly monitoring and regulating, ensuring each individual cell is performing with top-level efficiency without overheating. BMS is ...
The traction motors can produce adequate torque at any speed, from a full stop to 125 mph (200 kph), without needing to change gears. Why Diesel? Diesel engines are more efficient than gasoline engines, and when moving literal tons of freight or passengers, efficiency is paramount. Train ...
Under the hood of the Honda Ridgeline, Pilot and Passport, you’ll find the same engine block and heads used to power the 550-horsepower, twin-turbocharged Ridgeline Baja race truck across hundreds of miles of desert. Some might say this is over-engineering; we say it’s engineering at its...
As such, a-Si is well understood and is commonly used in solar-powered electronics. It does, however, have some drawbacks. One of the biggest problems with a-Si solar cells is the material used for its semiconductor. Silicon is not always easy to find on the market, where demand often ...
We've just discussed how to achieve efficiency from the engineering side, and how, enabled by simulation, engineers can push design boundaries to meet these challenges. There’s also a boundary being pushed from the organizational side to help engineers be more efficient. Currently the automotive ...
The two kinds of rewards worth pursuing: e-bike credits to offset the 10 cents/min. cost of having an electric motor whir you along, and a choice of e-gift cards that require higher point totals. In less than a year after I started seriously taking advantage of the program that I had...
On a workforce level, employees in this model need to be engaged enough, to put in the hours without getting burned out, and to make enough high-quality code each hour to recover from setbacks and power through. This way, they can achieve efficie...
How to calculate motor efficiency for variable-speed centrifugal pumps: knowing the efficiencies of the pump, VSD, and motor will enable the engineer to calculate the kW input for a pump, from minimum to maximum flow and head conditions for that pump. Here, the author goes through that ...
