adding a sprocket to a motor

1. First catch your sproket gear.

2. If the motor shaft has no flat - file a small one.

1. Slide sprocket gear onto the shaft, align the grub screw and tighten it like mad.

Worked for me.

that simple? okay thanks. so I guess a machine shop would better do the job for more precise and balanced jobs.

know any site with pictures?

The motor shaft is probably some standard size, and may, or may not, have a flat or keyway on it. You just have to buy a sprocket that will fit the shaft diameter, and has a setscrew to secure it to the shaft (works best with a flatted shaft), or that takes a key to match the keyed shaft.

It is now. Someone will have to post a schematic for a PWM controller for an arc welder. ;-)

You can also buy weld-on sprockets, for which the installation method should be self-evident, at least in principle.

BTW, this isn't really an electronic design question.

The sprokest ar jsut plain sprockets you weld onto a hub, the hup you attach to your motor shaft.

For the likes of a bike, I'd think you need a keyed shaft and hub, and a key.

and maybe some grease too?
