Latency in flux observation has an adverse effect on the performance of observer-based field-oriented speed control for three-phase induction ... The first control design is devoted to flux control ...

BILBAO, Spain - June 3, 2025 - ABB has achieved an industry first by gaining Environmental Product Declaration (EPD) status for the Gearless Mill Drive (GMD) ring motor, an essential technology used ...

Being a central part of the motor core, rotor design is critical to motor performance and efficiency. Because electric motors can spin at up to 20,000 rpm and even more, the permanent magnets have ...

Research and development efforts also play a vital role in refining these design options. BLDC motors are often specified to maximize efficiency and torque density, and open rotor designs can further ...

DeepDrive’s dual-rotor design promises material efficiency and range improvements but remains in the lab. In contrast, Donut motors are already in production. The company’s motorcycle motors ...

That motor features a unique dual-rotor design and is currently in the testing phase.

In this paper, an energy-saving scheme in rotor field-orientated vector control is developed for induction motor drives. The energy-saving scheme minimizes copper ... Electrical loss minimization ...

The motor is currently in the testing phase and features a unique dual-rotor design. It aims to redefine the efficiency, range, and performance of electric vehicles. This innovation pioneers a ...

They require brushes to make electrical contact with the central rotor and this leads to steady wear. By contrast, AC induction motors based around the squirrel-cage design pass the current through a ...

“Sailing knowledge is coming back to shipping,” explains Luke McEwen, technical director at Anemoi Marine Technologies, as he sets out how Anemoi’s Rotor Sails are designed for minimal structural ...
