In this paper, a synchronous/permanent magnet hybrid(SynPM) machine is presented. It is shown that the machine has good power density and efficiency, and that the machine has true field regulation capability. The principle of operation, finite element analysis and simulation of this new machine are investigated in the paper.

The unique merits of internal permanent magnet synchronous machine (IPMSM) make it a good candidate for automotive industrial applications. This paper presents the design of an internal permanent magnet synchronous machine having fractional slot configuration with single layer concentrated winding arrangement. The electromagnetic analysis has been performed using finite element analysis via ANS...

This paper deals with a fault-tolerant semi-12-phase permanent-magnet synchronous machine (PMSM) used for electric vehicles. High fault-tolerant and low toque ripple features are achieved by employing fractional slot concentrated windings (FSCWs) and open windings. Excessive magnetomotive force (MMF) harmonic components can lead to thermal demagnetization of rotor magnets as well as high core l...

Permanent magnet synchronous motors (PMSMs) are efficient motors which have widespread applications in electric industry due to their noticeable features. One of the interesting applications of such motors is in underwater vehicles. In these cases, reaching to minimum volume and high torque of the motor are the major concern. Design optimization can enhance their merits considerably, thus reduc...

These last thirty years were outstanding by the revolution of technology possibilities in the field of digital electronics and this, as much as within context of programmable solutions like (Microcontroller, DSP,...etc), than of reconfigurable solutions (CPLD, FPGA). Among all these possibilities, Field Programmable Gate Array (FPGA devises) is a good compromise between the advantage of the fle...

Rao-Blackwellied particle filter is a stochastic filter combining Kalman filters with particle filters. It is suitable for models that could be decomposed into linear and nonlinear part. Since the conditionally linear part can be solved by the Kalman filter, the sequential Monte Carlo is run only on the non-linear subspace. The resulting algorithm is a parallel evaluation of multiple Kalman fil...

Vector control has been widely used in control of permanent magnet synchronous motors (PMSM) where the information of rotor position is required. Shaft position sensor such as an optical shaft position encoder or Hall Effect sensor is fitted to provide a signal that is used to maintain an appropriate space angle between the stator and rotor fields in the motor. Even though this method is very p...

This paper proposes the use of H-bridge inverter for feeding a Permanent magnet Synchronous Machine (PMSM) in Electric Vehicle (EV) applications which allows the power transferred from the electrical source to the mechanical load and on the other hand to operate in degraded operating mode even though with one or several phases nonsupplied. In this first an existing method such as three phase in...

<p>This paper describes a novel fuzzy tracking control for permanent magnet synchronous motors (PMSM) using an extended Kalman filter (EKF) and disturbance observer (DO). The goal is to create robust controller able drive the system’s states track virtual reference model provide low effect on machine. First, PMSM represented Takagi-Sugeno (T-S) attended by load torque variation. Next, To ...
