I don't know for sure why this would happen - it has not happened to us. But the first thought would be that there is supposed to be a seal of some kind below the motor. Its purpose would be to prevent water from the tank from splashing or misting up into the motor area, during flushing or during travel. A parts diagram of the toilet might show such a seal, if it exists.

I do recall that the entire motor is enclosed in a tightly fitting black rubber sleeve. If that sleeve is missing or ripped or otherwise does not seal well, the motor will exposed to a salty mist, which will corrode it.

You might check both possibilities.
