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 ...

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 ...

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 ...

Just like the foot bone's connected to the leg bone, it's only natural to think that a car's engine is connected to its rear wheels. This seemingly reasonable assumption would be wrong—at least in ...

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.

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 ...

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 ...

Whether you’re reading about V8 pickups or electric sedans, the concept of torque is critical to understanding the capabilities of a car. Torque often takes a back seat to horsepower when it comes to ...

The first step in attaching a wheel to a vehicle is to start the hardware by hand, making sure the bolts go on smoothly and evenly. After that, an impact wrench fitted with an impact torque stick can ...
