The PMSM is superior to both induction motor drives and DC motor drives because of the inherent advantages of these mo...

The aim of this project is to model a six step discontinuous current mode inverter fed to a Permanent Magnet Synchronous Motor (PMSM) drive using MATLAB/SIMULINK. The dq-axis Voltage-Current and Torque relation in terms of machine parameters are used along with a six step 120 degree mode inverter and gate drive using MATLAB/SIMULINK. There is also a provision for easy changes to the machine par...

The dual motor drives fed by a single inverter are purposely designed to reduce size and cost with respect to single motor drives fed by a single inverter. This paper presents the speed responses behavior of Dual Permanent Magnet Synchronous Motor (PMSM) driven by Mean and Differential Torque Control technique. The drive is simulated by using Hysteresis Current Controller. MATLAB/Simulink is ch...

This study presents a novel means of designing a simple and effective torque controller for Permanent Magnet Synchronous Motor (PMSM). The overall stability of the system is shown using Lyapunov technique. The Lyapunov functions used contain a term penalizing the integral of the tracking error, enhancing the stability. The tracking error is shown to be globally uniformly bounded. Simulation res...

Permanent Magnet Synchronous Motor (PMSM) drive is being preferred in industrial automation due to high efficiency, compact structure, and high torque to weight ratio and so on. PMSM have been widely used in variable speed drives. The direct torque control (DTC) technique for a PMSM motor is receiving increasing attention due to the important advantages as the elimination of the current control...

This work introduces a novel permanent-magnet synchronous machine (PMSM) architecture that employs rotational asymmetry to increase the torque density output in constant power variable speed applic...

The use of permanent magnets (PM) is increasing in permanent magnet synchronous machines (PMSM) to fulfill the requirements of high efficiency machines in modern industry. PMSM are widely used in industrial applications, wind power plants and the automotive industry. Since PMSM are used in different environmental conditions, the long-term effect of NdFeB-based magnets at high temperatures and t...
