Dear friends I am trying to build a circuit which can control and drive a Berger Lahr 5 phase stepper motor (RDM 5913/50). The stepper motor can carry around 2 amps on each winding. The circuit I have built is very simple and consists of an lm555 to produce a.

Stepper motors is a brushless DC motor that rotates in discrete steps, and are the best choice for many precision motion control applications. Also, stepper motors are good for positioning, speed control and applications which require high torque at low speed.

In previous tutorials of MATLAB, we have explained that how to use MATLAB to control DC motor, Servo motor and Home appliances. Today we will learn how to control Stepper Motor using MATALB and Arduino. If you are new to MATLAB then it is recommend to get started with simple LED blink program with MATLAB.

Modes of operation in Stepper Motor Before you start coding for stepper motor you should understand the working or rotating concept of a stepper motor. Since the stator of the stepper mode is built of different pairs of coils, each coil pair can be excited in many different methods, this enabling the modes to be driven in many different modes. The following are the broad classifications Full Step Mode. In full step excitation mode we can achieve a full 360° rotation with minimum number of turns (steps). But this leads to less inertia and also the rotation will not be smooth. There are further two classifications in Full Step Excitation, they are one Phase-on wave stepping and two phase-on mode. One phase-on stepping or Wave Stepping: In this mode only one terminal (phase) of the motor will be energised at any given time.

This has less number of steps and hence can achieve a full 360° rotation. Since the number of steps is less the current consumed by this method is also very low. The following table shows the wave stepping sequence for a 4 phase stepper motor. Step Phase 1 (Blue) Phase 2 (Pink) Phase 3 (Yellow) Phase 4 (Orange) 1 1 O O O 2 O 1 O O 3 O O 1 O 4 O O O 1 2.

Two Phase-on stepping: As the name states in this method two phases will be one. It has the same number of steps as Wave stepping, but since two coils are energised at a time it can provide better torque and speed compared to the previous method. Although one down side is that this method also consumes more power. Step Phase 1 (Blue) Phase 2 (Pink) Phase 3 (Yellow) Phase 4 (Orange) 1 1 1 O O 2 O 1 1 O 3 O O 1 1 4 1 O O 1 Half Step Mode The Half Step mode is the combination of one phase-on and two-phase on modes. This combination will help us to get over the above mentioned disadvantage of the both the modes. As you might have guessed it since we are combining both the methods we will have to perform 8-steps in this method to get a complete rotation. The switching sequence for a 4-phase stepper motor shown below Step Phase 1 (Blue) Phase 2 (Pink) Phase 3 (Yellow) Phase 4 (Orange) 1 1 O O O 2 1 1 O O 3 O 1 O O 4 O 1 1 O 5 O O 1 1 6 O O O 1 7 1 O O 1 8 1 O O O Hence, it is your choice to program your stepper motor in any mode, but I prefer Two Phase-on stepping Full Step Mode.
