Abstract:
During a long time, permanent magnet synchronous motor (PMSM) were only reserved for some
specific applications, however, recently, these machines are becoming more used due to the powerful magnetic
characteristic of the rare earth, being used in different areas. Recently several researchers have proposed
implementations combining the use of permanent magnet synchronous motor with the direct torque control (DTC)
technique offering a quick and precise control. The present work combines these techniques and it proposes th ....etc

INTRODUCTION
The alternator are of salient pole, brushless revolving field type and self excited by an overhug AC exciter(rotating armature type)through a rotating rectifier assembly. The machine is itself regulated through a generator controlled unit (GCU) which controlled excitation to the exciter field.
CONSTRUCTION
STATOR
The stator winding consist of coils wound either with synthetic enamel copper wires or with bare copper bars and with suitable slot insulation
ROTOR
The rotor consists of shaf ....etc

Abstract
This paper introduces a sensorless nonlinear control
scheme for controlling the speed of a permanent magnet
synchronous motor (PMSM) driving an unknown load torque.
The states of the motor and disturbance torque are estimated via
an extended nonlinear observer avoiding the use of mechanical
sensors. The control strategy is an exact feedback linearization
law, with trajectory tracking evaluated on estimated values
of the PMSM states and the disturbance torque. The system
performance is evaluated by simulations.

Optimal Designs and Comparison of the Doubly
Salient Permanent Magnet Machine and
Flux-reversal Machine in Low-speed Applications

Abstract
The subject of this is to optimize the design and to compare
The performances of a low-speed doubly salient permanent magnet machine with
Those of a low-speed flux-reversal machine devoted to direct drive applications. The
Optimization, focused on the maximization of the machines mass-to-torque ratio,
is done by a genetic algorithm combined with the finite-element method (FEM) ....etc

Abstract
This paper present a speed control technique for effectively meeting the motion control objective which is
a permanent magnet synchronous motor (PMSM) based on an embedded inside current tracking objectives. The tracking

ABSTRACT
Permanent magnet synchronous motor (PMSM) has been widely used in high performance drive applications for its advantages such as compactness, high efficiency, reliability and suitability to environment. Due to its high power density and smaller size, PMSM has evolved as the preferred solution for speed and position control drives on machine tools and robots. A Permanent Magnet Synchronous Motor (PMSM) is a motor that uses permanent magnets to produce the air g ....etc
