[Frank Herrmann] had an interesting idea to turn a geared DC motor into a servo motor assembly, but with a stepper motor-like interface. By stacking some small PCBs behind the motor body, it was ...

It is an engineering truism that there is no such thing as a perfect solution—just the best solution for the problem at hand. That holds particularly true for servo motors and stepper motors. Both are ...

Stepper motors produce accurate, computer-controlled motion for applications such as robotic arms and paper-feed mechanisms for printers. They require current pulses delivered through a special ...

Brushless servo motors are all the hype these days. But stepper motors still provide a number of advantages while being more cost efficient and robust. Together with precision linear and rotary ...

Stepper motors are impressive little engines that may not be getting the credit they deserve, as they are a relatively important part of our electronic lives. Printers and CNC machines are ...

Engineers rely on motion-control devices to improve efficiencies and production rates on automated factory floors, or at least maintain them. One family of such devices, stepper motors, is widely used ...

The amount of noise in a motor depends on the type of motor, environmental conditions, and the specific application. Permanent magnet and hybrid stepper motors are generally quieter, as they have a ...

Stepper and servo motors have different attributes when considered for motion applications. Torque curves play an important role in selecting the proper size and type of motor for an application.

Kevin Teresa based in Switzerland has created a new open source stepper motor driver board with 6A / phase and 48V capabilities enabling it to drive a wide variety of stepper motors from NEMA 17 to ...

3D scanners aren’t cheap, and the last thing you want to see after purchasing one is bad data. But that’s what [Dave Does] and others were getting from their Revopoint POP scanners until some communal ...
