SPEED CONTROL OF BRUSHLES DC MOTOR

Abstract

The main goal of today’s applications and future applications are high efficiency
and low manufacturing cost. Now these goals are achieved by the use of brushless DC motors
(BLDC) in a more number of applications. The BLDC motor has various applications used in
industries like in drilling, lathes, spinning, electric vehicles, elevators, home appliances where
BLDC replace the conventional brushed DC motor. Further, the BLDC motors offer a good
control which is very much required for the vehicles and they are suitable for variable speed
applications. They can be used where space is less because of its compact size. So in this
paper overview of BLDC motor MATLAB simulation of open loop speed control technique
and close loop control techniques are represented.
