[Tobias Kuhn] had watched a YouTube video about a robot arm which used servo motors, and wanted to try making one himself. But he found it hard to get slow or smooth movements out of the servos. Even ...

Potentiometers, or variable resistors, are a standard component that we take for granted. If it says “10k log” on a volume pot, than we fit and forget. But if like [Ben Holmes] you are modelling ...

grbl is stepper motor controller firmware for three-axis cnc machines, intended to run on Arduinos with a motor driver add-on board. Engineer in Wonderland cnc-related blogs are indexed here It is the ...

As the shift to automation continues to gain momentum in the industrial sector, servo motors and stepper motors with electric actuators become ever more important. When selecting a motor for an ...

Bipolar stepper motors provide precise position control while operating in an open loop. Industrial automation applications—such as robots and processing and packaging machinery—and consumer ...

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 are often used for positioning since they are cost-effective, easy to drive, and can be used in open-loop systems—meaning that they don’t require position feedback like servo motors.
