Just replaced brushes and put it back together - Running Problems

I have a CFBN 125A-3 I just replaced brushes and put it back together and it stutter runs.

I mean it runs and turns off over and over as though someone is plugging it in and out. Can You Help?

Friend, it seems clear to me that if the problem didn't exist before your re & re the motor, and now the problem is there, it is something you did or didn't do on the rebuild.

I hope someone that rebuilds electric motors reads this and can offer so guidance.

Cheers,

Bill
