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 ...

Prior to the advent of the adjustable-speed drive (ASD), the polyphase induction motor operated as a constant-speed motor. Figure 1 shows the well-known torque and current curves versus speed for the ...

There are many drive technologies and solutions available that are generally suitable in cases where a central opening is needed. In practical use, however, each has its own disadvantages. With hybrid ...

Still can't figure out the difference between horsepower and torque? Here's the simplest, plain-English guide to engine power ...

Welcome to the dark world of torque converters. When it comes to automatic-equipped street machines and drag-race cars, the torque converter is a welded-up magic box that few enthusiasts know much ...

The latest force torque sensors provide the levels of sensitivity and reliability needed for industrial cobot applications.
