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 ...

Alongside the top speed and the dash from zero to sixty, horsepower is often what, on paper at least, makes one car seem ...

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 ...

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 ...

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 ...
