The most important charactreristics include the input interface. The most common options are:. Another important feature of a stepper motor driver is if it is only able to control the voltage across the winding, or also the current flowing through it:.

Another feature of the motor that also affects control is the arrangement of the stator coils that determine how the current direction is changed. To achieve the motion of the rotor, it is necessary not only to energize the coils, but also to control the direction of the current, which determines the direction of the magnetic field generated by the coil itself see Figure 8. In stepper motors, the issue of controlling the current direction is solved with two different approaches.

In unipolar stepper motors , one of the leads is connected to the central point of the coil see Figure 9. This allows to control the direction of the current using relatively simple circuit and components. As pointed out above, this approach allows a simpler driving circuit only two semiconductors needed , but the drawback is that only half of the copper used in the motor is used at a time, this means that for the same current flowing in the coil, the magnetic field has half the intensity compared if all the copper were used.

In addition, these motors are more difficult to construct since more leads have to be available as motor inputs. In bipolar stepper motors , each coil has only two leads available, and to control the direction it is necessary to use an H-bridge see Figure This solution requires a more complex driving circuit, but allows the motor to achieve the maximum torque for the amount of copper that is used.

With technology progress, the advantages of unipolar are becoming less relevant, and bipolar steppers are currently the most popular. There are four different driving techniques for a stepper motor:.

Now that we understand the working principles of the stepper motors, it is useful to summarize their pros and cons compared to other motor types. To summarize, stepper motors are good when you need an inexpensive, easy-to-control solution and when efficiency and high torque at high speeds are not necessary.

Due to their properties, stepper motors are used in many applications where a simple position control and the ability to hold a position are needed, including:. Did you find this interesting?

Remember me. Essentially, stepper motors offer excellent speed control, precise positioning, and repeatability of movement. Additionally, stepper motors are highly reliable since there are no contact brushes in the motor. This minimizes mechanical failure and maximizes the operation lifespan of the motor.

These motors can be used in a wide range of environments, as many different rotational speeds can be achieved because the speed is proportional to the frequency of pulse inputs.
