From Stepper Motor power supplies, a deleted link-only answer contained some useful links,
Tenuously following on from Laundry in Thailand, the coin operating box often suffers problems, namely the coin slot and the control PCB. The former suffers from failure to register a coin. The latter sometimes fails to start the washing machine.
Following on from Kossel 3D Printer, and the tutorial videos (see Kossel construction videos) the BuildA3DPrinter kit comes with an extruder stepper motor with a planetary gearbox. This results in a very high torque. However, as stated below, it has been replaced by the 3325_0, a motor with the same NEMA size and same torque.
Are you baffled by the numbers used to describe the plethora of RC motors which are available for multirotor fliers? So was I. So here is a brief description of what I have discovered whilst trying to make sense of it all. Continue reading RC Motors
From the question on SE Robotics, DC Motor Control, a link to a SparkFun tutorial, Basic DC Motor Circuits, was provided. Continue reading A tutorial on Basic DC Motor Circuits
I found a stepper motor at the night market just off Pracha Songkro, for 10 baht Continue reading Mitsumi M49SP-3K
