This paper presents an online stator resistance estimator to achieve precise torque control of CSI fed PMSMs over a low speed operating region. A quick and precise control several researchers have proposed implementations combining the use of permanent magnet synchronous motor with the direct torque control (DTC) technique. The electromagnetic torque, stator flux and rotor position can be estim...

Abstract: In this paper, we present the modeling, analysis, and realization of current vector control for a permanent magnet synchronous motor (PMSM) drive using MATLAB/Simulink and a field programmable gate array (FPGA). In AC motor drive systems, most of the current vector controls are realized by digital signal processors (DSPs) because of their complete and compact hardware functions. Howev...

Direct torque control (DTC) is one of the most prominent techniques used by permanent magnet synchronous motor (PMSM) drives in industry applications. Nevertheless, presence hysteresis controllers and inaccurate voltage switching table traditional DTC results higher flux ripple. This study proposes an enhanced functioned Surface-mounted PMSM (S-PMSM) drive with mitigation The operation relies o...

Reliability is a fundamental requirement in electric propulsion systems, involving particular approach studies on system failure probabilities. An intrinsic improvement to the involves introducing robust architectures such as fault-tolerant motor drives these systems. Considering potential for hardware failures, design will achieve reliability objectives without recourse optimized redundancy or...

Core loss is one of the significant factors affecting the high power density of permanent magnet machines; thus, it is necessary to consider core loss in machine design. This paper presents a novel method for calculating the core loss of permanent magnet synchronous machines under space vector pulse width modulation (SVPWM) excitation, taking magnetic saturation and cross coupling into account....

In this research paper, the performance of an air-cored axial flux permanent magnet synchronous generator is evaluated for low speed, direct drive applications using 3D finite element modeling and experimental tests. The structure of the considered machine consists of double rotor and coreless stator, which results in the absence of core losses, reduction of stator weight and elimination of cog...

This letter proposes a general single-sensor active damping framework for LCL -equipped high-speed permanent magnet synchronous machines. By the proposed method, arbitrary assignment and stability resonance within Nyquist frequency are achieved with only inverter-current feedback or motor-curre...
