New layout for a 2-speed might be light and compact while maintaining efficiency Could potentially allow strong launch with a lower-cost motor unit Idea might be due in future Lucid EVs, or engineers ...

Prior to the advent of the adjustable-speed drive (ASD), the polyphase induction motor operated as a constant-speed motor. Figure 1 shows the well-known torque and current curves versus speed for the ...

PSC motors rely on the rotating magnetic field that is generated by the applied alternating voltage and corresponding alternating current to turn the rotor. The magnetic field rotates at 3,600 rpm (60 ...

There's no better way to meter precisely the right amount of torque to each corner of a vehicle than assigning each wheel its own electric motor. But that's way too expensive for everyday vehicles, so ...
