This machine uses a three-phase Dahlander motor, which has three operation modes: stop, half speed, and full speed. The motor uses a special mechanical switch to select the operating mode.

Enrico shows how his Infineon TLE94112EL motor controller shield can be put to work through a simple Arduino sketch.

Arduino simplifies things by only using just one coding language. Here's what you need to get started with developing software for the tiny device.

Rather than write a bunch of stepper motor code himself, he installed and ran a four-axis fork of grbl on the Arduino, turning it into a stepper motor controller.

Maker, developers and hobbyists that enjoy building Arduino platform based projects might be interested in a new Arduino Motor Shield called the Arc controller which has been created by Arc ...

A. The controller must have one of the following ratings [430.83(A)]: 1) Horsepower rating — controllers, other than circuit breakers and molded-case switches, must have a horsepower rating not less ...

I wasn't aware of this one, though it launched in April: the self-explanatory Arduino AI Assistant (the AAA). There are three main, possible, development wins identified. One is to generate code more ...

All questions and answers are based on the 2011 NEC. Q. What is the Code rule for motor control circuit overcurrent protection? A. Motor control conductors that aren’t tapped from the branch circuit ...
