Electric fans commonly use low-cost AC motors built around capacitors, which now increasingly demand replacement due to high power consumption. However, while three-phase brushless DC (BLDC) motors ...

It’s impossible to balance line-to-line voltages perfectly in three-phase circuits, so they typically differ by a few volts or more. However, if voltage unbalance exceeds 1%, it can markedly decrease ...

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 ...

The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...

In the original version of this article, the second figure contained an error. The image has been updated. It’s important for engineers to have a good, working ...

KAWASAKI, Japan--(BUSINESS WIRE)--Toshiba Electronic Devices & Storage Corporation ("Toshiba") has today started to provide engineering samples of a gate driver [1] IC, "TB9084FTG,” for three-phase ...

Early incarnations of the electric motor first appeared in the 1740s through the work of Scottish Benedictine monk and scientist, Andrew Gordon. Other scientists such as Michael Faraday and Joseph ...

Electric motors, which convert electrical energy into mechanical energy, play an essential role in a variety of industrial and robotics applications. Given that electric motors account for ...

Innovative Swedish boutique carmaker Koenigsegg has revealed a new 6-phase electric motor for its four-seat Gemera supercar that establishes new benchmarks for power density. The Dark Matter motor ...
