The schematic of a PMSM drive using a DTC-based speed loop PDFF controller is shown in Fig. 1. This DTC scheme is implemented in stator flux frame, which requires knowledge of stator flux in ...

In a speed controller, the motor’s speed (or velocity) is being controlled. There is an element that detects speed, whether it be a tachometer or some sort of encoder. This monitoring element provides ...

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 ...

GKN Automotive has started trials of the world-first all-electric car equipped with two-speed transmission and torque vectoring between front wheels. Extensive winter testing are performed in Arjeplog ...

Anytime force—either a push or a pull-is applied to an object and an opposite reaction takes place, work happens. For example, when meathead's El Camino breaks down and he pushes it home, work occurs.

This file type includes high resolution graphics and schematics when applicable. Today’s machine-tool shops need high speeds and high torques to quickly and efficiently carve complex parts out of ...

We try a Jeep Renegade with GKN’s latest self-contained electrified rear-axle with torque vectoring from a single motor. There's no better way to meter precisely the right amount of torque to each ...

The amount of automotive tools that have been invented to both save time, and promote accuracy, is a seemingly endless list. When it comes to achieving accuracy for a crucial aspect of safe driving, ...
