Speed Control Strategy of Permanent Magnet Synchronous Motor Drive Using SPWM Technique

Abstract

This paper present simulation model in MATLAB and Hardware of PMSM Drive using ATmega 328 controller & SPWM technique. A Inverter fed converter of a PMSM drive execute using this simulation model and Hardware. Now a days in many electrical application a Brushless Dc Motor (BLDC) & DC motor being used. But in recent time PMSM become the best alternative to the convectional motor as well as BLDC motor. It has low cost, high efficiency, variable speed is very high & power density is high. Permanent Magnet Synchronous Motor (PMSM) is used in industrial application, automation, aerospace, & traction industries because of its high torque. PMSM carry only magnet i.e. permanent magnet on rotor side. Sinusoidal Pulse Width Modulation (SPWM) technique is used to control speed of PMSM.
