intended to spin only one direction. Possibly the brushes are mounted
angular or offset to the shaft allowing only one direction of
rotation. If thats the case it will not work, for long anyway.


I think the CW could mean one of two things. As you mentioned, the
burshes are not mounted perfectly symetrical, but rather optimized so
spinning on one directin is more efficent or powerful, or some such.

The would mean the brushes are not dead-on-balls-accurate (an industry
term) 180.00 degres.

The other possibility is that the thread on the screw is such that if
the motor spun the opposite way, the pulley would just spin off.

Since these are custom motors, the label could reflect either of the
above.

Testing would show the differences.
