L6203 Stepper Motor Driver Circuit. This small post shows how to control speed and direction of rotation of bipolar stepper motor using arduino uno board and l293d motor driver chip. The stepper motor used in this example is just a pc cd rom or dvd rom drive which has 4 wires.
The l6203 is a dmos full bridge driver which can handle the high peak current up to 5a and supply voltage up to 48v with rds on of just 0 3 ohm. This small post shows how to control speed and direction of rotation of bipolar stepper motor using arduino uno board and l293d motor driver chip. A lot of driver circuits are available on the market today.
X nucleo expansion boards and x cube software.
The stepper motor used in this example is just a pc cd rom or dvd rom drive which has 4 wires. L6203 l297 h bridge stepper motors driver circuit now is a year that i m working on cnc numerical control machines and after various experiences realize this bridge h stepper 50a motor speed control circuit for model car boat. L6203 l297 h bridge stepper motors driver circuit now is a year that i m working on cnc numerical control machines and after various experiences realize this bridge h stepper motor capable of driving motors up to 4 amper type pure bipolar 4 wires or up to 5. This note explains the basics of stepper motor driving and describes the drive techniques used today.
