PERMANENT MAGNET SYNCHRONOUS MACHINE
AIM:
To design and simulate a Permanent Magnet Synchronous Machine.
CIRCUIT DESCRIPTION:
A three-phase motor rated 1.1 kW, 220 V, 3000 rpm is fed by a PWM inverter. The PWM inverter is built entirely with standard Simulink blocks. Its output goes through Controlled Voltage Source blocks before being applied to the PMSM block's stator windings. The load torque applied to the machine's shaft is originally set to its nominal value (3 N.m) and steps down to 1 N.m at t = 0.04 s.
Two control loops are used. The inner loop regulates the motor's stator currents. The outer loop controls the motor's speed.
RESULT:
Thus a Permanent Magnet Synchronous Machine was designed and simulated.
