Porsche just reaffirmed that the Taycan will have a 2-speed rear transaxle when it comes to final production. What improvement in acceleration times and range should we expect with this more complex ...

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 ...

A single-speed motor has one rated speed at which it runs when supplied with the nameplate voltage and frequency. A multispeed motor will run at more than one speed depending on how you connect it to ...

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 ...

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 ...

Full-voltage, single-speed motor starters: Single-speed squirrel-cage motors have starters that fall into two categories: full-voltage or across-the-line starters; and reduced-voltage starters.
