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 ...

Open-loop stepper motors have held a prominent position in automation applications over the years due to their simplicity, excellent positioning, and low cost. However, as manufacturers utilize faster ...

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 ...

They do this with greater efficiency and less motor heating because motor phase currents are regulated up and down according to need. Performance of the closed-loop steppers are similar to servo ...

Brushless dc (BLDC) motors are widely used in industrial and home applications, such as in HVAC blowers, because of their efficiency and cost advantage. Furthermore, sensorless control of BLDC motors ...

A Texas-based startup has raised US$4.5 million in seed funding to develop and commercialize a remarkable electric motor technology. The father/son team claims the design can massively reduce the size ...

Forbes contributors publish independent expert analyses and insights. William covers motorbikes, E-bikes, cars, trucks and mobility tech. With the electric vehicle (EV) market heating up and due to ...

While clutch and gearbox assemblies in washing machines have been replaced with belt-driven induction motors with tachometer feedback, digital-control algorithms will enable direct drive from ...

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 ...
