Abstract: In Brushless DC (BLDC) motor ripple-free torque can be produced by preshaping the excitation currents with the help of electronically controlled commutators. This ripple-free torque ...

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 ...

Higher-than-normal operating voltages give steppers better torque at high speeds — but watch that current! • The inductance in a stepper-motor phase winding limits how fast current rises when power is ...

A new technique implemented in a sensorless motor controller chip performs carefully timed sampling of phase currents, giving excellent torque regulation in brushless dc-motors. Ramesh T. Ramamoorthy, ...

Abstract: The current control of the D and Q axes of Permanent Magnet Synchronous Motors (PMSMs) is crucial in drives, especially when saliency is present in the system. The stability and performance ...

StepSERVO closed loop integrated motors from Applied Motion Products control position, velocity and torque for higher acceleration rates and faster machine cycles in food & beverage applications.

Building a 3D motor printed motor is one thing, but creating a completely custom servo motor with encoder requires some significant engineering. In the video after the break [365 Robots] takes us ...

Salvaging a beefy motor is one life’s greatest pleasures for a hacker, but, when it comes to using it in a new project, the lack of specs and documentation can be frustrating. [The Post Apocalyptic ...

Open-loop motors previously working in this system elevated the temperature of fluids being pumped into the bioreactor. The higher temperatures, in turn, adversely affected biological processing times ...
