The [Denki Otaku] YouTube channel took a look recently at some stepper motors, or ‘stepping motors’ as they’re called in Japanese. Using a 2-phase stepper motor as an example, the stepper motor is ...

The AMIS-30521 and AMIS-30522 stepper motor driver ICs allow engineers to eliminate the need for switches, Hall sensors, flyback diodes, and many passive components in applications ranging from ...

Rated for a 12- to 48-V dc input voltage, Haydon Kerk's DCM4826X stepper-motor drive module features a continuous output current rating of 2.6 A rms (3.68 A peak) per phase Rated for a 12- to 48-V dc ...

The fundamental circuit shown in Figure 1 generates timing for a two-phase stepper motor from an oscillator, as well as a direction (forward or reverse) signal. Figure 2 depicts the typical timing ...

Here's a simple algorithm that uses conventional microcontroller blocks to control commercially available H-bridges to properly commutate a bipolar stepper motor through a microstepping profile.

Step motors provide accurate position control without the need for feedback, traditionally in open-loop control schemes. A stepper motor’s shaft normally makes discrete angular movements of ...

Bipolar stepper motors are used in many applications, from driving paper through a printer to moving an XY stage in industrial equipment. Typically, the motors are driven and controlled by inexpensive ...

Accuracy, size, and quiet operation make these motors an intelligent choice for medical devices. When selecting a stepmotor for a medical device, engineers need to consider many factors. For example, ...

Frequently, when it comes to step motor selection, users will select a motor with the highest holding torque rating, assuming that it will give them optimal performance. However, it is an improper ...

[TBJ] is building what he calls a junkbox 3D printer. You can probably guess that he’s trying to salvage most of the parts for the device, and after pulling a stepper motor from an old printer he was ...
