In this paper, a new composite sensorless control scheme for permanent magnet synchronous motor (PMSM) drive via generalized proportional integral observers (GPIOs) and Kalman filter (KF) is proposed.

In this study, an MRAS-based sensorless control scheme of permanent magnet synchronous motor (PMSM) drives using extended state observer (ESO) is proposed to enhance the robustness to large load ...

Used to rotate the drill string during the drilling process, the top drive is a motor that is suspended from the derrick, or mast, of the rig. These power swivels boast at least 1,000 horsepower ...

USB 2.0 external hard drives won’t work. Because they won’t work, you’ll need to connect your external hard drive to one of the two USB-A ports on the back of the PS5. The USB-A port on the ...

So how does it work? The seemingly bizarre Harmonic Drive gear is actually rather genius in how it functions – its flexible-ellipse-within-a-circle setup creates a wobbling motion as it turns ...
