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 ...

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 ...

To successfully follow a velocity profile, a motor and drive combination must generate enough torque to: accelerate the load inertia at the desired rates, and drive the load torque at the desired ...

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.

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 ...

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 ...

Torque is the unsung hero of engine specifications, and we talk about it often. But does it get the recognition it deserves? Too often it ends up playing second fiddle to horsepower in the symphony of ...
