This paper compares three direct control strategies por induction machines, analizing it’s performance for electric vehicle tration. The stretegies analysed are DTC, DTC with PI controllers and PTC, driving an motor a mechanical dinamic model of as the load. Simulation shows that all suitable to use in EV traction, but modulation results better current THD torque/flux ripple. Between classic pr...
The synchronous homopolar motor (SHM) with an excitation winding on the stator and a toothed rotor is good alternative to traction induction motors for hybrid mining trucks. main problem in design of SHM electric drives that magnetic flux forms three-dimensional loops and, as result, lack high-quality optimization methods, which leads need overrate installed power inverter. This article discuss...
The rapid spread of electric vehicles is pushing for more and compact reliable e-axle architectures. In this scenario, the integration on-board battery charger with traction drive can be a feasible way to reduce embedded volume number components. Anyway, integrated chargers often present safety issues due absence an isolation stage. work, solution proposed integrating road equipped 6-phase moto...
Background: The currently accepted treatment of scoliosis are bracing and surgery. Two-stage anterior and posterior spinal fusion is used to correct scoliosis. It seems that the application of a longitudinal force to the axis of the spinal column as a means of stabilizing by halo traction, may increase the correction of the curve. The aim of this study was to evaluate the effect of halo tractio...
