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 ...

Tudor was lucky enough to be in Wales just as Sebastien Loeb was securing his 8th World Rally Championship title during Wales Rally GB 2011 and wrote a guest blog for ITV News covering the rally ...

The name of the game is acceleration at the wheels. Not motor torque. It’s common practice for EV producers to report the torque of the car’s electric motor. But Peter Rawlinson, Lucid’s chief ...

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, ...
