This paper presents torque-angle characterization of a Synchronous Reluctance Machine (SynRM). Advancement in power electronics and machine design have allowed these motors to be used in various industrial and traction drive applications. An appropriate torque-angle characterization can reduce the size of the converter and provide an optimal operation of the machine. It also gives insight about the...
This article is about measurement-based modeling of PMSMs. Typically, these machine designs feature nonlinear characteristics regarding the stator phase currents and show rotor angle dependent behavior. Thus, non-sinusoidal linked fluxes as well as higher torque harmonics occur. As this cannot be represented by classical dq0-based theory, a feasible modeling strategy had do be established and its...
In this paper, a multi-phase induction machine drive utilising the brush dc machine operation principle is presented and implemented on a cage rotor multi-phase induction machine. The results from measurements prove that the proposed brush dc control method for multi-phase induction machine drives produces remarkable results in the sub-base and flux weakening speed regions of the drive. It is found...
This paper proposes the use of an integrated low cost SAW torque sensor to improve the dynamic performance of permanent magnet servo drive systems including rotor position detection. A start-up procedure that enables machine control at and from zero speed is discussed and results presented to illustrate performance.
