I bought one of those motors from spares to go, it lasted 6 minutes before burning out, i called them and they did send a replacement the next day, that lasted 6 weeks before blowing in a customers house, fusing the machine and causing the smoke alarm to go off!!!
To be fair to them after the second one blew they offered me a full refund and also paid for the motors to be returned to them.
Maybe it was a bad batch!!
