A stepper motor is a DC electric motor that divides a full rotation into steps. This type of motor is a popular choice for robotics and automation applications. A stepper motor is a brushless DC electric motor that divides full rotation into equal steps. The steps are spaced evenly apart to ensure that the movement of the stepper is smooth and constant.


There are two main types of stepper motor drivers: single phase and two phase. Both have their pros and cons. Single phase and wave drive have similar step sizes but different torques. In some cases, a single phase driver may be the best choice, but it should not be the only one. The angular resolution of these motors is improved by half-stepping.

To ensure a proper stepper motor driver, it is important to consider the voltage and peak current limits. Unlike a DC motor, a stepper motor can't be operated at high speeds, so the driver must be able to accommodate both the voltage and resistance of each phase. The driver must also have a continuous current rating that is higher than the motor's peak current rating.

A stepper motor driver uses a separate source for its input. A clock signal is used to give the stepping command, while a reset signal sets the final level signals in a defined start position. Other signals that determine the operation mode of a stepper motor include the direction signal and the half/full signal.
