Can Motor Knocking

[regme]

Hi

 

I bought this12v can motor, and when it starts up there is some knocking put as I feed the power up to 12v it disappears, before I right it off it there anything I can do about the knocking.  Is just just because it's new it needs to be run in and for how long?

 

Cheers

That's likely to be bent shaft, imbalance or some 'internal derangement': most likely to degrade further with more operation. Return for refund or replacement if that's possible.

Thanks, no worries, it was worth a shot
