To be fair to Dyson the motor fan assembly is only around $25 as a spare part. I buy them for the Columbus at work, and they are tenth of the price of the OEM part, and have the same life. There are really only around 8 different motor fan units among all the cleaners, from the low end to the top of range industrial units. The only exceptions are the real cheapies that last around 20 hours of use, and the really big ones with TEFC motors that can inhale bricks.
