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.

The primary feature of stepper motors is listed right within their name: their ability to ‘step’ forwards and backwards, something which they (ideally) can do perfectly in sync with the… ...

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 ...

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.

Figure 3 By changing the pushbutton in Figure 1 to a dpdt switch, you can make a stepper motor run clockwise and then counterclockwise without microprocessor control. Related articles: Stepping motor ...
