Product Details

• Product Type: mini stepper motor
• Model: 28BYJ-48
• Package contains: 1x 28BYJ-48 5V Mini Stepper Motor

28BYJ-48 is the most commonly used stepper motor because of its compact size 5V power supply (that can be provided by any controller) and a high level of control. It has a stride angle of 5.625�/64 hence it will make 64 steps to complete one rotation (as every step covers  5.625) so it has a high level of control. This stepper motor has 4 coils unipolar arrangement (as it is 4 phase motor) and each coil is rated for +5V power supply so it can be controlled easily controlled by any microcontroller.

28BYJ-48 stepper motors consume high current so motor driver like ULN2003 Motor driver module is mandatory to drive this motor. It consumes +5V so can not give high torque for high torque prefer NEMA17.
