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 ...

• The inductance in a stepper-motor phase winding limits how fast current rises when power is applied. • Series-resistor current limiting needs higher voltages for faster step rates, but higher ...

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 ...

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 ...

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 ...

The detail that a force exists on a wire carrying a current in a magnetic field has an interesting application when we consider a current carrying loop. When the area vector is at right angles to the ...

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 ...

Most electric cars aren't normally associated with performance, but they are able to achieve something gasoline-powered cars can't: peak torque at zero rpm. It's thrown around often, and many will ...

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 ...
