Have a Kenmore sewing machine motor marked 110/120/Volt, A.C.-D.C. 25/60 Cycles, 1.2 Amps. Want to control speed with Arduino. Any thoughts?
Thanks.
How is this related to the Sparkfun website?
As implied by codlink, it would be a good idea to move this to a more relevant Sparkfun forum.
Anyway, you should be able to use a leading-edge dimming module to control that type of motor (presumably a “universal” type motor). For manual control you could use a cheap dimmer from the hardware store, but for Arduino control have a look at this:

This was discussed here:
The Inmojo board has many design issues that render it unsafe. Hopefully they will respin it and fix the problems, but until then, I would go with a safer layout.
Yep. Since the schematic is provided, it would be pretty easy to re-spin it and get some cheap boards made at Itead / Seeed Studio.n1ist:

The motor is probably inductive (meaning its speed is determined by the AC cycles, 60 hz, and the number of windings). Changing power to it changes its power output but not its speed.
You’ll need a DC motor and a motor controller board to vary speeds. The inventor’s kit has small DC and servo motors to play with and get the easy concepts down.
