The aim of this paper is to investigate the behaviors of line-start permanent
synchronous machine. The LSPMSM is a high efficiency synchronous motor with
self starting capability when operating from fixed frequency voltage source. The main
objective here is to implement the simulink simulation of LSPMSM and use the
simulation to explore the behavior of the ponents during the starting run
of the motor from standstill. And also to examine the ability of the motor to
synchronize with various values of field strength by apply deferent values of
izing current, mechanical load and rotor inertia .
1 Introduction
As with most motors, the synchronous motor (SM) has two primary parts. The
non-moving is called the stator and the moving, usually inside the stator, is called
the rotor. SM can be built in different enable the motor to rotate two
fluxes are needed, one from the stator and the other from the this purpose
several motor configurations are possible. From the stator side three-phase motors
are the mon. There are mainly two ways to generate a rotor flux. One uses
rotor windings fed from the stator and the other is made of permanent s and
generates a constant flux by itself. To obtai
