A research team has developed a novel method for estimating the predictability of complex dynamical systems. Their work, ...

Figure 1 An LPVCO with 10-octave (20 Hz to 20 kHz) tri-wave output comprises antilog pair Q1 and Q2, two-way current mirror ...

The rise of Tesla has created a rift between mechanics and car owners. Software updates can’t fix worn bearings or degraded ...

Abstract: This paper proposes a two-loop position/speed control system for linear DC motors. The control system is based on the parameterization of lead compensator using the genetic algorithm (GA) ...

The Ariya e-4orce gets up with the go, but flubs the stop. It's been a strange year in California, with benign-sounding atmospheric rivers absolutely drenching the state—causing both calamity (immense ...

Abstract: The performance of the linear reluctance oscillating motor operating under AC and DC supplies is presented. The motor under AC supply must be equipped with a capacitor connected to the ...

Novel bi-phase piezo motor enables accurate linear motion in an extremely compact package. (Nanowerk News) PI, a global leader in nanopositioning, precision motion control systems, and air bearing ...

permanent magnet synchronous motors (PMSMs), and brushless DC motors. Each brings trade-offs in efficiency, cost, and performance. Among the many technologies driving the electric vehicle ...
