Tool Review: NEMA 23 Stepper Motor Covers

Over the last year I have been finishing a project to convert my X2 manual mini mill into a fully enclosed 3-axis CNC milling machine. Once I had the stepper motors mounted and running, I worried that the wire connection at the base of the motors might be a potential weak point in the design. Eventually I want to use mist coolant when machining parts but I do not want to run the risk of shorting out the wiring due to spotty connections.

How-To: Use a Stepper Motor as a DC Generator

[youtube=http://www.youtube.com/watch?feature=player_embedded&v=cPMkBfuo824&showinfo=0] MAKE pal Dino Segovis brings us this handy tutorial on running a stepper motor in “reverse,” i.e. turning the shaft mechanically in order to generate electrical power, instead of the normal usage. He writes: Any electric motor will also output a voltage when it’s freely spinning. Stepper motors are much better at this because […]
