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 ...

ZF presents its new 140 kW 2-speed drive unit for electric cars (scalable up to 250 kW), which consists of an electric motor, 2-speed transmission and power electronics - all integrated into a compact ...

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 ...

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 ...

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 ...

A brushless-DC motor is common in ceiling fan and pan-tilt-zoom (PTZ) camera designs. But you can’t use the same brushless-DC motor solution for both of these end products. A ceiling fan driver ...

This file type includes high resolution graphics and schematics when applicable. This 8051 microcontroller-based control circuit adjusts the speed of a small permanent-magnet dc motor via photosensors ...
