My Emotator 747 rotor motor now fails to turn right, but turns left just

I removed the rotor this morning and put it on the bench, same thing.

Removed the top and bearing ring.  Inside looks fine.  Watched motor as I
applied power LEFT
and no problems.  When applying power RIGHT, motor starts to move and makes
a snap noise, as if
it is internally jammed from moving that direction.

I will check the current both ways, but expect RIGHT to be higher since
there is a jam.

Anyone have any experience with a DC rotor motor that will only turn one

I suppose getting a replacement motor will not be fun :-(
