This paper proposes a new method for online identification of stator winding temperature for an open-end winding (OEW) permanent magnet synchronous motor (PMSM). The method exploits the zero sequence current (ZSC) due to the third harmonic back electromotive force (EMF) circulating in the system in order to estimate the phase resistance, which, in turn, is used to derive the winding temperature. In order to do this a proposed idea of maximum zero sequence current amplitude along with the actual ZSC amplitude and the electrical speed of the motor is used. The temperature is estimated without any additional sensors in a wide operating speed range. A single synchronous phase-locked loop (PLL) is utilised in order to obtain the required parameters. The independence of the rotor position grants the possibility for the exploitation of the proposed winding temperature estimation method in a variety of control techniques including the sensorless control to increase the robustness of the overall system.

“…It should be noted that the injection of 3rd integer multiplier harmonics (triplen harmonics) is not possible in PMSMs driven by conventional three-leg (see Figure 1a) inverters when the phase windings of the machine are arranged in a star connection. On the other hand, due to the decreasing cost of electronic power switches, the six-leg inverters are now an interesting alternative to three-leg systems in terms of increased reliability [11][12][13]. The application of knowledge from the literature regarding the dual-fed open-ended winding PMSM (see Figure 1b) enables the development of new, more effective methods for improving the energy conversion quality in electrical machines (by modulating the phase currents by higher harmonics and, in particular, by injecting zero-sequence harmonics).…”

This paper deals with the torque ripple minimization method based on the modulation of the phase currents of the permanent-magnet synchronous motor (PMSM) drive. The shape of the supply current waveforms reducing the torque ripple of the machine considered was determined on the basis of finite element analysis (FEA). In the proposed approach, the machine is supplied by a six-leg inverter in order to allow for the injection of zero sequence current harmonics. Two test PMSMs with fractional-slot concentrated windings (FSCW) and surface-mounted permanent magnets (SPMs) have been examined as a case study problem. Wide-range fractional analyses were performed using developed numerical models of the electromagnetic field distribution in the considered machines. The results obtained show that the level of torque ripple in FSCW PMSMs can be effectively reduced by the modulation of the phase currents under the six-leg inverter supply.

“…The dual-fed OEW configuration has found a wide range of applications such as wind power generation [4], [5], electric vehicles [6], [7], high power electric propulsion [8] and aircraft starter-generator systems [9]- [11]. Two isolated dc power supplies [12], one dc supply and a floating bridge [13] or a single dc supply [14] can be adopted for the dual-fed OEW. While on one hand the common dc bus configuration significantly simplifies and reduces the costs of the topology, on the other hand it allows the ZSC to flow freely in the system.…”

In this paper a dual-fed common dc-link topology Open-End Winding Permanent Magnet Synchronous Motor (OEW-PMSM) for aircraft high speed Starter-Generator application is considered. While on one hand the common dc bus configuration significantly simplifies and reduces the costs of the topology, on the other hand it allows the Zero-Sequence Current (ZSC) to flow freely in the system. High speed machines are characterized by low phase inductance which implies low Zero-Sequence Impedance (ZSI). A small time constant of the zerosequence circuit produces a high frequency, high intensity ZSC ripple with the risk of harming the switching devices. This paper presents a novel hybrid Space Vector Pulse Width Modulation (SVPWM) that allows to instantaneously eliminate the Zero-Sequence Voltage (ZSV) produced by the two Voltage Source Converters (VSCs) by square wave modulating one of the two VSCs. The non-sinusoidal machine back Electro Magnetic Force (back EMF) has been considered and the effect of the converters' Dead Time (DT) on the ZSV has been analysed. The square wave modulated VSC uses IGBT devices while the other uses SiC technology. The proposed topology is tested through both simulations and experiments.
