Abstract: Cogging torque in interior permanent magnet synchronous motors (IPMSMs) is caused by variation in magnetic reluctance between permanent magnets and stator slot openings. It can result in ...

Abstract: This paper presents a semi-analytical model for predicting cogging torque based on harmonic interaction principle within the airgap. It derives the airgap’s magnetic energy through Fourier ...

Nidec Instruments has announced a new range of high-accuracy AC servomotors with battery-free magnetic absolute encoders, as ...

In a previous era, the line in the sand for racing wheels was drawn between those with force feedback, and those without. Today it’s about direct drive vs. belt-driven force feedback, and with the ...

Specifically, it delivers an ultra-smooth, cogging-free steering experience, powered by an axial DD motor which doesn’t judder or feel grainy when it sends resistance through your hands like ...

A UK manufacturer of sustainable, rare-earth-free electric motors, has unveiled a second generation of its motor technology, ...
