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 ...

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 ...

TOKYO--(BUSINESS WIRE)--Renesas Electronics Corporation (TSE:6723), a premier supplier of advanced semiconductor solutions, today introduced a family of motor driver ICs for brushless DC (BLDC) motor ...

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 ...

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.

There's no better way to meter precisely the right amount of torque to each corner of a vehicle than assigning each wheel its own electric motor. But that's way too expensive for everyday vehicles, so ...
