Abstract: Brushless dc motor still suffers from commutation torque ripple, which mainly depends on speed and transient line current in the commutation interval. This paper presents a novel circuit ...

Abstract: In this paper, a new control method for matrix converters is proposed which allows, under the constraint of unity input power factor, the generation of the voltage vectors required to ...

Screw piling offers significant benefit over both traditional concrete foundations and other piled solutions. This presentation will cover a range of areas relating to screw piling, starting off with ...

This could be the result of a worn or poorly adjusted transmission, a worn torque converter or even something simple like a low transmission-fluid level. So that’s job one: Check the level of fluid on ...
