ISE 10 motor fault

[ron]

I have had this fault on two machines recently so thought it was worth posting for info and to see if anyone else has had the same problem.
The rotor had come adrift from the motor shaft. Because the shaft is splined the motor still runs but the rotor is able to slide back and forward on the shaft, rubbing on the front and rear end fames.
My first customer complained about the noise, so running the machine with no belt soon pointed me to the motor. The second customers symptoms were not so obvious. She said the timer was not counting down. The door would not open and the motor was not running. No mention of noise. There was no fault code.
Turns out the loose rotor had moved to the back of the motor and rubbed through the insulation on one of the tacho wires causing intermittent shorting to earth. Replacing the motor has solved all the problems.
Any one else had this fault?

Hi Ron, yes i’ve changed a motor for this , was a bugger to diagnose as it was intermittant . I dismantled the motor for a looksee , looked as though the rotor hadn’t been driven on to the shaft hard enough , meant to show it to kenny . will drop it into him this week .

Re: ISE 10 motor fault

Hi John, I have not dismantled either of my faulty motors yet. Does it look like we may be able to repair them or is replacement motor the only alternative.
I will be taking one of the motors to the meeting in case anyone is interested in seeing this fault.
