[Raynerd] wanted a new spindle for his CNC machine and thought that a brushless DC motor would be a great platform to build from. [Raynerd] started with an off the shelf motor that had an 8mm shaft.

[Levi] whipped up his brushless DC motor design in OnShape ... you can just use off-the-shelf gear and hack it to make it work. Here, we support both methods.

Brushed motors are cheaper and simpler, but require maintenance and replacement of the brushes over time. Brushless DC motors rely on internal noncontact sensing devices and external electronics to ...

Their commutation can be brushed or brushless. The speed of a brushed DC motor can be controlled by changing the voltage alone. By contrast, an AC motor is powered by alternating current (AC) which is ...
