I had the same trouble recently.
Shipped a motor to a member of this forum. The motor had been shipped from Germany to a UK dealer, as a favour he said he's ship it to this forum member to cut shipping costs down to me then him.
Now bear in mind it had got from Germany to the UK unscathed but down to Essex it got the foot broken as well which didn't matter as it was a foot and flange motor and the feet were not needed. This was Yodel as a carrier and it was clearly marked.
"Please throw underarm "
However the fan guard had been bashed that heavily it had cracked a plastic fan blade.
Fortunately motors are very resilient provided they don't have a pulley or fan on them if dropped that normally come out unscathed except for the dangly off bits. I have seen largish fan motors get dropped off ladders and suffer no damage except for a few scratches and the fan end which usually ends up flat.
It's that common an occurrence that the motor people keep covers and fans as spares, so spares were shipped and all was well.
Carl as an aside what KW was that motor and how much, if you don't want to say either in public or in a PM I understand.
