We always think it is interesting that a regular DC motor and a generator are about the same thing. Sure, each is optimized for its purpose, but inefficiencies aside, you can use electricity to rotate ...

It’s fair to say that building electronic gadgets is easier now than it ever has been in the past. With low-cost modular components, there’s often just a couple dozen lines of code and a few jumper ...

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 ...

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 ...

The Five-Axis Integrated Stepper Module (FAISM) controls up to five stepper motors and includes a stepper translator so output connects directly to the motor. Five channels of SSI encoder feedback are ...

Stepper motor linear actuators (SMLAs) combine a stepper motor, precision lead screw and nut in one compact envelope, providing a highly configurable, customizable and robust system for linear motion.

Find a downloadable version of this story in pdf format at the end of the story. Take a look at a modern motor controller and one of the first things you'll notice is that the control circuit is about ...
