28BYJ-48 – 5V Stepper Motor

What is 28BYJ-48 – 5V Stepper Motor

We will introduce 28BYJ-48 – 5V Stepper Motor by its pin configuration, technical specification, and etc.

Pin Configuration

No:Pin NameWire ColorDescription
1Coil 1OrangeThis Motor has a total of four coils. One end of all the coils are connect to +5V (red) wire and the other end of each coil is pulled out as wire colors Orange, Pink, Yellow and Blue respectively
2Coil 2Pink
3Coil 3Yellow
4Coil 4Blue
5+5VRedWe should supply +5V to this wire, this voltage will appear across the coil that is grounded.

Where to use 28-BYJ48 Stepper Motor

The most regularly utilized stepper engine is the 28-BYJ48 Stepper Motors. You can discover this (or comparable) engines in your DVD drives, Motion camera and a lot more spot. The engine has a 4 loop unipolar course of action and each curl is evaluated for +5V subsequently it is generally simple to control with any fundamental microcontrollers. These engines has a walk point of 5.625°/64, this implies the engine should make 64 stages to finish one revolution and for each progression it will cover a 5.625° consequently the degree of control is likewise high. Be that as it may, these engines run distinctly on 5V and consequently can’t give high torque, for high torque application you ought to consider the Nema17 engines. So in the event that you are searching for a conservative simple to utilize stepper engine with better than average torque then this engine is the correct decision for you.

How to use 28-BYJ48 Stepper Motor

These stepper motors consume high current and hence a driver IC like the ULN2003 is mandatory. To know how to make this motor rotate we should look into the coil diagram below.


As should be obvious there are four loops in the engine and one finish of all the curl is attached to +5V (Red) and different closures (Orange, Pink, Yellow and Blue) are taken out as wires. The Red wire is constantly furnished with a steady +5V supply and this +5V will be crosswise over (stimulate) the curl just if the opposite finish of the loop is grounded. A stepper engine can be made to turn just if the loops are stimulated (grounded) in a legitimate arrangement. This intelligent arrangement can be modified utilizing a microcontroller or by structuring an advanced circuit. The grouping wherein each curl ought to be activated is appeared in the table beneath. Here “1” speak to the curl is held at +5V, since both the parts of the bargains at +5V (red and opposite end) the loop won’t be empowered. So also “0” speaks to the loop is held to ground, presently one end will be +5V and the other one is grounded so the curl will be empowered.
