Advantages of bldc motors are their higher speed ranges, higher efficiency, better speed versus torque characteristics, long operating life, noiseless operation etc.[5]. the structure of bldc motor is similar to that of a dc motor but the main difference is nothing but the absence of brushes and commutators. in bldc motor commutation is done electronically and during this process rotational the motor.the bldc motor is initially made to rotate in clockwise direction, but when the speed reversal . direct torque control of a bldc motor based on computing technique www.iosrjournals.org 3 page command is obtained, the control goes into the clockwise regeneration mode [7], which brings the rotor to the standstill position. instead of waiting for the absolute standstill position

Brushless dc motor speed control using microcontroller 1g.santhoshkumar, email: 1santhoshg92@gmail.com,2saexee@tce.edu abstract the hardware project is designed to control the speed of a bldc motor using closed loop control technique. bldc motor has various application used in industries like in drilling, lathes, spinning, electric bikes etc. the speed control of the dc motors вђ¦ the bldc motor is driven by a four-switch three-phase inverter in which the switches are triggered with respect to the rotor position as shown in fig. 7. the phase a terminal voltage with respect to the star point of the stator .

Sensorless drive bldc motor is widely used because of its advantages like high efficiency, high power density, torque, fast response and low inertia. fast dynamic response, higher steady precision a brushless dc motor consists of a rotor in form of a permanent magnet and stator in form of polyphase armature windings. it differs from conventional dc motor in such that it doesnвђ™t contains brushes and the commutation is done using electrically, using a electronic drive to feed the stator windings.
