Balancing shaft and motor

Posted by Marooned on June 21, 2012 at 11:46am

Hi there!

There are many descriptions and movies showing how to balance a propeller but I haven't found any clue on how to balance motor and attached shaft. I bought 4 EMP motors and it's extremely hard to attach the shaft to maintain the axis. Take a look on attached screenshot to see what I'm talking about. This creates pretty strong vibrations even if the and of shaft round a circle less than 1mm diameter.

Screws attaching this shaft were tighten well. Is it normal? Or is it because motors are "cheapo"?

Thanks.

    The pic shows a mounting screw missing. The one shown does not look very tight. Other causes might be bent shafts. These motors are relatively cheap and easily replaced. Try another one and see if the vibration is reduced.
