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 ...

Whether you’re reading about V8 pickups or electric sedans, the concept of torque is critical to understanding the capabilities of a car. Torque often takes a back seat to horsepower when it comes to ...

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.

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 ...
