Salvaging a beefy motor is one life’s greatest pleasures for a hacker, but, when it comes to using it in a new project, the lack of specs and documentation can be frustrating. [The Post Apoca… ...

Ac motor drives: The ac induction motor is sometimes considered a constant-speed motor, and it is when connected to a 60-Hz power source. However, its speed can be adjusted if power is supplied by ...

Apart from the harmonic drive, the engineering community hasn’t really come up with any clever mechanisms for speed-to-torque conversion in the last few decades. However, recently a few folks… ...

Small package, big impact: that’s the story behind Maxon’s new Air S mid‑drive motor. On the surface, it looks almost ...

The motor is capable of spinning 18,000 rpm, and the value of the two-speed transmission is indicated by the red and amber lines on the axle torque versus speed curve shown.

The result, says Linear Labs, is a truly remarkable motor that produces two to five times the torque density, at least three times the power density and at least twice the total output of any ...

Bafang has just unveiled its new H700 electric bicycle drive system, complete with a dual-speed automatic shifting motor and several other innovations as part of a complete e-bike drive package.

Electric vehicles (EVs) achieve rapid acceleration due to instant torque delivery from electric motors, fewer moving parts, and advanced power electronics. Electromotive force (EMF) in EVs drives ...

Indeed, the future for Linear Labs - and electric motor makers in general - is wide open when you consider how many millions of products in our modern lives require an electric motor, and how they ...

Torque is an irrelevant thing to quote, said Peter Rawlinson, the chief technology officer at Lucid Motors. I'm not interested in torque, the former chief engineer of the Tesla Model S.
