They typically work best below 1,000 rotations per minute (rpm) because torque falls off rapidly as speed increases. Stepper motors are named as such because they are commanded by pulses received from a drive to move in small discrete steps, and they can do so rapidly. This article describes how users can implement and control stepper motor systems. For lower speeds and smaller force requirements, stepper motors provide good motion resolution. Stepper systems provide some of the best features of the previously described motors, in an economical way.

Some users need better motion control than is possible with AC induction or DC motors but are looking for a more cost-effective option than servos.įor many applications, the answer can be stepper motor systems, consisting of a stepper motor, a drive, and a controller. The maximum speed for a 28byj-48 stepper motor is roughly 10-15 rpm at 5 V.AC induction motors and DC motors are useful for basic on/off and less precise variable speed applications, while servo motors combine high speed, torque, and position/velocity/acceleration precision via positive feedback-with correspondingly high cost and complexity. In the setup, you can set the speed in rpm with the function setSpeed(rpm). This allows you to easily control 2 or more stepper motors at the same time. You can create multiple stepper motor objects with different names and pins. Stepper liftmotor = Stepper(stepsPerRevolution, 8, 10, 9, 11). In this case I called the stepper motor ‘myStepper’ but you can use other names as well, like ‘z_motor’ or ‘liftmotor’ etc. To get the correct step sequence, we need to set the pins in the following order: 8, 10, 9, 11. For this we use the function Stepper(steps, pin1, pin2, pin3, pin4) where steps is the number of steps per revolution and pin1 through pin4 are the pins to which the motor is connected.

Next, you need to create a new instance of the Stepper class, which represents a particular stepper motor connected to the Arduino. This means it takes 2048 steps to rotate 360 degrees (see motor specifications above). In this example we will be using the motor in full-step mode. Next, I defined how many steps the motor takes to rotate 1 revolution. Include the Arduino Stepper.h library: More information about this library can be found on the Arduino website. The sketch starts by including the Stepper.h Arduino library. Step one revolution in the other direction:

Begin Serial communication at a baud rate of 9600: Stepper myStepper = Stepper(stepsPerRevolution, 8, 10, 9, 11) Create stepper object called 'myStepper', note the pin order:

* Example sketch to control a 28BYJ-48 stepper motor with ULN2003 driver board and Arduino UNO. Although it is not super accurate or powerful, it is a great motor to use for smaller projects or if you just want to learn about stepper motors.

The 28BYJ-48 is one of the cheapest stepper motors you can find.
