Description

We can control the speed of the single phase DC Motor (http://www.engineersgarage.com/dc-motor/tags/dc-motor) with ease by using microcontroller and proper driving mechanism.Inindustries mostly coil based analog variable frequency drive is used. Because of this type of variablefrequency drive there are problem rising like over current, short circuit, over voltage, under voltage, underfrequency which results in unwanted tripping of the devices.We can replace this coil based analog variablefrequency type with microcontroller based speed controlling mechanism. Because of this type of speedcontrolling, we can accurately control the speed of DC motor in operation. In addition to this, this type ofcontrolling comparatively cheaper, reliable and accurate .It requires less maintenance and it is moreconvenient in use.

Aim ofthisprojectis tocontrolspeed ofdcmotorusing

commands sent from mobile phone. As speed of dc motor is dependent on duration of input voltage, bychanging the duration we can control the speed of the single phase dc motor.

BLOCK DIAGRAM

DESCRIPTION OF BLOCK DIAGRAM:-

· AT89S52 controller of 8051family from ATMEL is the heart of the system which works on 5V DCsupply. It is used to control the operation of whole system.

· GSM has been provided to receive the commands sent from mobile phone and send to thecontroller AT89252.

HelloDishant Shah, few pointSubmitted by narayan gour on Mon, 23/03/2015 - 12:06

Hello

Dishant Shah,

few point i am not able to understand proper which i mention below:-1> where you defined PWM_BIT..?2> where is defination of a> motor_initialize()..? b> rotatemotorclockwise()..?3> you u r using timer0 but you have putted value of TH1 ..?why .?and alsostarting timer1 ...4> where we are going to increment the count value ?5>where is gsm related coding ?

plz plz if possible answer as soon as possible ...thanks in advance....my mail idis [email protected]

these files are included asSubmitted by SHAH DISHANT H. on Tue, 21/04/2015 - 22:18

these files are included as main.h

We will inform editor team to provide space by means of which we can sharefiles.

or else possible for you toSubmitted by narayan gour on Wed, 22/04/2015 - 11:07

or else possible for you to send me on my mail id ..plz send me [email protected]
