Abstract: In this paper we are studying a problem related to the traction of an electrical vehicle (EV). The power unit is a Permanent Magnet Synchronous Motor (PMSM) piloted by the trapezoidal control, strategy. The models of the electrical vehicle, of the motor based on finite element identification and the drive, are implemented under Matlab/Simulink 7.1. The control is ensured by four close...

The spoke-type permanent magnet synchronous motor (PMSM), which is a general ferrite magnetic flux-concentrated motor, has low portion of reluctance torque at the total magnitude. Therefore, as way to increase torque, there double-layer PMSM that can maximize difference in inductance between d-axis and q-axis. However, PMSM, cogging ripple, harmonic distortion (THD) with main cause vibration no...

Stator turn faults in permanent magnet synchronous motors (PMSMs) are more dangerous than those in induction motors (IMs) because of the presence of spinning rotor magnets that can be turned off at will. Condition monitoring and fault detection and diagnosis of the PMSM have been receiving a growing amount of attention among scientists and engineers in the past few years. The aim of this study ...

This paper compares the torque characteristics of single stator permanent magnet synchronous motor(PMSM) and double-stator PMSM under different split-ratios, air-gap lengths shaft diameters by finite element method. Firstly, effects split-ratio towards two motor structures are researched, results show that optimal split-ratios do not change lengths, is greater than single-stator, single-stator ...

This paper presents a comparative study on two simulation and an experimental models for Permanent Magnet Synchronous Motor (PMSM) drive system. A realistic modelling of PMSM system is very useful before developing study. In particular, analyzing the performance motor control algorithm in environment provides many advantages. The can be tested by using with various scenarios order to reduce tes...

The paper deals with real-time control of PM synchronous motor for sensorless position using Power PC-MPC processor. Real parametric-and real-time model could be ideal tools for both control and simulation of the PMSM (permanent magnet synchronous motor) position drive. Unfortunately that idealized model doesn’t exist so far. Such a model has to face following serious problems: it must be excit...

This paper presents some techniques for driving novel 5 phase dual winding PMSM (Permanent Magnet Synchronous Motor) the in-wheel motor. The motor realizes change over characteristics that can expand area from high-torque mode to high-speed due construction. However, structure makes a high-current ripple high coupling between windings. proposes control methods reduce current ripple, including i...

Accurate computing of the saturated inductances of Permanent Magnet Synchronous Machine (PMSM) is very important during the design process. In this paper, a new method is presented based on the B-H characteristic of the stator material and unsaturated inductances formulations. This method is used to calculate the saturated inductances of the axial flux PMSM. The synchronous inductance and all o...

This paper presents the application of the Linear Quadretic Gaussian (LQG) controller to the state estimation and feedback of a speed sensorless permanent magnet synchronous motor (PMSM) drive system. The nonlinear model of the motor has been linearized on the basis of field orientation principle. The standard Kalman filter technique has been used to estimate the speed, position, and load torqu...
