Are you saying manual help when power is applied?
I will assume you mean when not powered. The motor is a magneto, so there is magnetic resistance; they do not free-wheel. They will however spin with help when no power is applied, level of free-spin is dependant on applying force. You can feel the locking points in the turns where the magnetic collar will grab, it will feel lumpy.
There should also be no wobble in the shaft. (meaning you need to remove the squirrel cage and inspect the motor itself) If there is, the coil comes in direct contact with the magnetic collar and stops the polar inversion, which makes the motor spin. This resistive contact with the collar is also the cause of the dreaded screech, be it shot bushings or just dirt itself. Also check the clearance between the cage and the motor to make sure they do not come in contact. Mind this when re-installing the cage onto the motor shaft.
To test the motor, just apply 12Vdc.
