Hi!

I am into building electric bikes.

Can you give me any advice on how to install a sprocket to an electric
motor?

** Well, it is like this:

1. First catch your sproket gear.

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

3. 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.

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.

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

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.
