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 ...

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 ...

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 ...

When it’s time to specify a high-performance motor that offers both precise positioning and cost efficiency, stepper motors offer many advantages over DC motors thanks to their brushless technology.

We try a Jeep Renegade with GKN’s latest self-contained electrified rear-axle with torque vectoring from a single motor. There's no better way to meter precisely the right amount of torque to each ...

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