In an electrolytic capacitor-less inverter, source current harmonics are caused by LC-circuit resonance, and the power factor deteriorates. Therefore, inverter must reduce control without additional circuits. This paper proposes a method to in three-phase of permanent magnet synchronous motor drive. The proposed consists using full-state feedbacks LC-resonance state observer. validity is confir...

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...

This document deals with the design of a Permanent Magnet Synchronous Motor (PMSM) to peripherally drive counter-rotating pump inducer. The motor/pump is associated using rim-driven principle where motor’s active parts are located at periphery inducer blades. It proposes Halbach array permanent magnets for rotor motor. solution allows generation Sinusoidal Electromotive Force (EMF). Therefore, ...

This paper presents the traction motor evaluation method depending on the electric transmission energy transfer characteristics and different source of supply, including motor manufactures, diesel turbine manufacturers, wheel side reducer manufacturers and electric drive system integrated manufacturers. 9 evaluations are proposed in 3 levels from the motor body and control performance, electric...

As the core of electric vehicle, driving motor should have advantages high-power density, wide speed range and small volume. Aiming at demand vehicle drive structural characteristics permanent magnet synchronous motor, by using Motor Cad, a internal rotor (PMSM) was designed analysed in detail this paper. In order to improve anti-demagnetization ability power density structure as built-in compo...

in this paper, a new field oriented control scheme with maximum torque for permanent magnet hysteresis synchronous (pmhs) motor has been presented. vector control method provides significant improvement to the dynamic performance of ac motors but in this method d- axis current is controlled such as the ratio of motor torque to motor current is a maximum, then the dynamic performance will be ver...

The direct drive permanent magnet synchronous motor (DD-PMSM) is a suitable choice for high-precision position control applications. Among various control methods of this motor, the vector control approaches especially the field oriented control has a high-performance in the industrial drives. In this method, the components of stator current are controlled independently and as a result, the tor...
