Title: Brushless D.C. Motor with Phase and Width Control of the Rectangular Conduction Signals
Authors: Carmen Cojocaru-Filipiuc and C.G. Haba and A. Cretu
Abstract: A brushless d.c. motor (BLDCM) fed with rectangular current-blocks from a controlled-current voltage-inverter is considered. For a given d.c. supplying voltage the electromagnetic torque and the saturation speed can be regulated by the phase and width control of the feeding current blocks. The current lead phase-shifting with respect to the induced e.m.f. determines the speed increase in a constant power regime. The speed characteristic versus the current-control angle is studied by numerical simulation and an original system used for the BLDCM speed and torque control is presented .
