Digital Control of BLDC motor by using MOSFET and microcontroller

Abstract

Now a day BLDC motor is becoming very famous in the department of aerospace, automation, computers, military, household appliances and traction applications because of its high competency and low maintenance cost. Because of this the four quadrant operation of BLDC motor is extremely important. BLDC motor control requires rotor position and speed measurements. In this project the modeling of BLDC motor drive system along with its control system have been presented using H-bridge type arrangement MOSFET work like a drive and for controlling purpose we use microcontroller AT 89S52.
