Rotor won't turn due to rare earth magnets have to much magnetism. The generator was working fine and the bearings had to be replaced. After replacing bearings and reassembling the generator we were...
You do not say what type/model generator you have, so I will just give you some basics.
There is nothing wrong with the magnets. Their power did not change at all, their pwer never changes, except to degrade slightly over time (hundreds of years.)
The generator rotor is hitting the stator. In other words, the alignment of the rotor inside the generator is off center, making the rotor bind on the inside of the stator, resulting in a lock-up.
With the generator attached to the motor, remove the generator end, and slowly try to turn the engine over by hand. REMOVE THE PLUG WIRE FROM THE PLUG FIRST, so that the engine cannot start. Watch inside the generator, and discover why the generator rotor is not aligned. Pehaps the bearings were installed incorrectly, or the housing is installed incorrectly. Most generator engines have a tapered power-takeoff shaft, where the gen. shaft connects to it. Is this Bolt tightened to specifications? Is there some debris floating around in the gen. (such as a screw, or a pebble, or a nut) that would impede its movement?
