STEPMOTOR SM5776

SM5776 is one of the most popular stepper motors for all kinds of equipment. As an example these motors can be used in robotics, inspection machines, machine vision systems, pressure control devices, mini CNC machines and positioning stages.

To control SM5776 we recommend step motor driver SMD-4.2 or stepper motor controller SMSD-4.2.
