![]() Half step mode is a combination of the two full step modes (one-phase and two-phase). This mode provides the highest torque but it requires twice as much power as one-phase mode. In full step two-phase mode the driver energizes the two coils at the same time. ![]() This type of controlling requires the least amount of power but provides the least torque. In full step one-phase mode the driver energizes one coil at a time. The full step can be divided into 2 types: one-phase and two-phase. The popular controlling modes of of the stepper motor are: full step and half step. The other type is the unipolar stepper motor, it is 4-phase brushless motor which has 5 or 6 wires. The bipolar stepper motor is a two-phase brushless motor which has two coils (windings), this motor has 4 wires (2 wires for each coil). Stepper Motor Control with Arduino and Joystickīasically there are two types of stepper motors: bipolar and unipolar. The stepper motor used in this example is 28BYJ-48 which usually comes with its driver board. ![]() Now I’m going to show how to do the same thing with uinpolar stepper motor. In the last Arduino project, I made a simple motor controller which controls the speed and direction of rotation of CD-ROM bipolar stepper motor.
