This is a topic which we addressed in our recent article on the workings of stepper motors, with particular focus on the 4-phase 28BYJ-48 stepper motor and the disadvantages of steppers versus servos.

Figure 1 Here is how a typical 2-phase hybrid stepper motor looks like. Source: Monolithic Power Systems How microstepping works. It’s possible to move a stepper motor less than a full step. This ...

Although stepper motors have resolutions typically between 25,000 and 50,000 counts per revolution, the motor is a spring-mass system under load and the typical resolution is 2,000 to 6,000 counts ...

Very nice project. As described in the video, for servo motor v dumb stepper, servo motor is more efficient and servo motor won’t miss steps, or at least not without being able to provide a warning.

For example, a motor with a torque of 2.3 N m at 500 rpm when used with a 3:1 gearbox will have a 6.9 N m output, but the motor’s rpm will climb to 1,500 rpm to drive the gearbox.

It is small, at 1.6 inches (40 mm) square, and provides up to 2 amps drive current for one axis and up to 1 amp for the second, with an optional second stepper or bi-directional dc driver daughtercard ...
