Stepper motor#

The Stepper motor block describes how to interface a stepper motor with Arduino boards. It simulates both a unipolar and a bipolar stepper motor.

Note

The type of stepper motor only affects the physical connection to the Arduino microcontroller.

Block properties can be divided into:

identifying (Stepper motor name and Motor step number variable name), form a unique name for the block and step number variable;
settings of the stepper motor itself.

In the block property Stepper motor name the name of the motor in the model is written, thanks to this property several blocks with different names can be placed on the model, when forming the C source code of the model there will be no copying of blocks. The Motor step number variable name property specifies the “name” of the variable that stores the number of steps taken by the motor. The property is necessary for forming the correct structure of the C source code of the model.

Stepper motor settings include the following properties:

Stepper motor speed – determines the value of the stepper motor rotation speed, [rpm];
Delay time – the time for which the rotation of the stepper motor is delayed is set, [μs];
Number of motor steps – The number of steps that the stepper motor must take in 1 revolution is indicated, [step];
Stepper motor connection pin numbers №1, 2, 3, 4 – the pin numbers of the Arduino boards to which the stepper motor or motor driver is connected are written.

Important

The stepper motor is controlled by digital pins 8, 9, 10 and 11 for unipolar or bipolar motors. If more complex compound examples need to be implemented, the stepper motor must be connected via a driver to the microcontrollers.

Important

The block input can be supplied with rotation speed values in the range from 0 to 180 ̊ .
