Re: F&P Smartdrive GW701-U problem

I am struggling to understand the design of this stator assembly. I thought that is I could glue the locating tabs back on (with Araldyte) and get them to last even a few minutes, then I could confirm that there was nothing else wrong. Unfortunately, with the torque from the motor, they lasted seconds, not minutes.

I am not sure however if this is the real problem. The reason I have my doubts is the two metal plates and 4 screws that hold the stator. One plate has bushings attached which protect the screws from the stator torque. However the holes in the stator through which the bushings protrude are larger than the bushings. This is allowing the slewing. If the slewing is undesirable, why are the holds in the stator so large? Also, why are the plates greased? It seems as though it is designed to allow the slewing.

The next trick I am thinking of trying is packing around the bushings to fill the stator holes and reduce the slewing that way. However, I wonder if that will cause a different problem.

Penguin,

Thanks for confirming the problem.

Further details

I forgot to mention that before I disassembled the unit, I observed the stator during the wash cycle (though the little access door in the front). It was slewing back and forth on each change of direction by 1 – 2 cm – hence the clunking.
