Small brushless motors and LiPo batteries are one of the most impressive bits of technology popularized in recent years. Just a few years ago, RC aircraft were powered by either anemic brushed motors ...

In today’s world, motors are ubiquitous, powering everything from household appliances to industrial machinery. The importance of optimizing motor control for energy efficiency cannot be overstated, ...

What You’ll Learn: The origins of Permanent Magnet Brushless DC motors (PMDC). How the efficiency of electric motors increases as you increase the number of phases. How to optimally control stators as ...

Understanding where losses occur and how to minimize them is key to improving performance across servo systems.

When the U.S. Department of Energy (DOE) issues the final versions of it its long-awaited fan efficiency test and efficiency standards rules over the coming months, it will apply regulations to a ...

Energy efficiency is one of the most misunderstood aspects of fractional horsepower motors and gearmotors. It normally does not receive much attention; however, efficiency can be critically important ...

Most servomotors have an efficiency in the range of 50 to 60%. But it is possible to devise positioning-motor architectures that deliver far better efficiency. One such class of devices is the Maxon ...

Energy efficiency always carries a price, and the federal government’s latest initiative to wring more savings from efficient electric motors offers proof. The U.S. Department of Energy (DOE) has ...

For motor applications, engineers have several options at their disposal. Typically, engineers can choose between direct-current (DC) or alternating-current (AC) motors. Machine Design has covered the ...
