Stepper motors are employed in a variety of applications across the engineering spectrum because they are inexpensive, simple to operate, and offer high torque at low speeds. However, stepper motors suffer from drawbacks such as missed steps, decreased torque at high speeds, resonances, and high power consumption. In order to mitigate these issues, Galil has three methods of closing the loop around a stepper motor: End point correction, closed loop microstepping, and driving the stepper motor as a 2-phase brushless motor.
In this white paper, Galil Motion Control explains how this works and when to choose the different methods. Read the full white paper here (link).
