Hi, i am Anil from India.

i am making a line following robot in that the motors which i am using as wheels are rotating very fastly.

how to control the speed of the motor. i heard that by PWM we can control.

if any body has the schematic or datasheet or documents on controlling thedc motor plz send me

the motor has 3 wires i think +ve, -ve and gnd

thank you in advance.

my email is: [email protected]
 
You have DC brush motor with two armature wires +ve, -ve. The standard PWM amp in velocity mode maybe used for velocity control - see Elmo products (www.elmomc.com). But low cost SCR control with higher form factor (see Baldor or Control Techniques products) may be suggested also.
