Performance Analysis of BLDC Motor Drive for Feed Drives

In this article presents an analysis of speed control of Brushless DC (BLDC)motor for feed drives. The feed drives play a crucial role in CNC machines. BLDC motor has been progressively replacing conventional DC drives in various applications due to its brushless and low power-loss operation. In this paper three phase voltage source inverter fed BLDC motor control is analysed. The proposed model has been developed using Simulink/MATLAB and also their speed and torque performance for various load conditions using PI Controller. are analysed.
