![]() 28BYJ-48 Stepper Motor PinoutĬoil 1 – Coil 4: These 4 coils are used to control the logical sequence (step sequence).ĥV: This pin is used to supply the stepper motor by 5V. Let’s take a look at the 28BYJ-48 stepper motor pinout in this picture down below which have a 5-wire. The 28BYJ-48 stepper motor is commonly used with a ULN2003A driver which we will talk about it in this tutorial. One of the main characteristics of this Motor is the speed variation ratio (1/64) which we will talk about it after a while, and this motor is a uni-polar stepper motor with (34.3 mN.m) torque and (15 RPM) speed at 5V rated voltage. There are many types of stepper motors but in this tutorial, we will talk about the 28BYJ-48 stepper motor which is a small, low-cost stepper motor that is used in many small-scale robotics and Arduino projects. What Is The Main Purpose Of A Stepper Motor?Ī Stepper motor is a DC motor that rotates in discrete small (steps), this type of motor is recognized as having high torque at low speed in addition it can determine positioning in a very accurate way which makes it the ideal choice for many applications: robotics, CNC machines, automation, 3D printer, and DVD players.Interfacing Stepper Motor With Arduino Usnig ULN2003 Motor Driver.
