Hmmm. Is the NEUTRAL somehow being confused with the safety ground, 
or is the motor wired like an isolated ground (that is, insulated 
from ground, but grounded via a dedicated green wire)?  

The NEUTRAL must NOT be grounded at the motor (and must be bonded to 
ground only at the service or at the stepdown transformer that 
creates a new system), but the FRAME of the motor certainly must be 
grounded. I can imagine it being tricky to install a motor in such a 
manner that it is NOT grounded locally.
