Hardware Implementation of Field-Weakening Algorithm for BLDC Motor Drives

Abstract

Brushless DC (BLDC) motors and their drives have been progressively considered in an expansive scope of uses because of their noteworthy highlights. The construction and uncommon highlights of these motors have arranged a reason for easier control and reduced size contrasted with different motors with a similar power. This exploration work shows an improved Field Weakening (FW) calculation for BLDC motor.
The proposed technique is robust to the parametersof d-and q-axis inductances. Furthermore, this proposed procedure is joined with the DTC technique to achieve angreat performance drive in the FW area. A recreation model of proposed drive has been created utilizing MATLAB and equipment model was produced for the proposed BLDC drive. The reenactment and equipment results are given in this report to demonstrate the adequacy of the proposed approach..
