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 ...

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 ...

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

Speed reducers are mechanical devices generally used for two purposes. The primary use is to multiply the amount of torque generated by an input power source to increase the amount of usable work.

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 ...
