I would bite the built and get a new motor and controller from one of the dealers then you will know it will work. But please do not let that guy anywhere near it

I 100% agree ! Permag motors are DC devices.
Someone, I think it was John suggested that the power FET in the controller had gone (short circuit), replacing it would be an easy and cheap fix.
John Rudd:
Ok.....
I'll stick my neck out here and offer to repair the controller... :zap: :zap:
I have the technical know how and the means to test...( trumpet fanfare .... :lol: )
Paul if you want to take me up on my offer send me a pm please...
pmdevlin:
Thanks John, (and others!) Ill take you up on it please, I am Wirral, I will PM you, and will naturally pay for services, successful or not!
I have challenged the guy but he keeps coming back with the fact it has a big spec sticker on the motor, and it says "AC". I too also think he has fried the motor, inadvertently, but as he is the "expert" should he have known this? .
So, just to get it straight in my head, I will be picking up the controller and motor tomorrow. I understand the inside of a DC motor, or at least what it looks like. Would an AC motor be visually different externally? If so, Ill push for him to foot the bill, but I doubt I will be successful if it looks the same externally. (back to the flippin AC sticker on the can!)I would have thought in my simple way, he could have plugged the controller in to power,, turned on the pot, and measured what was going on at the output lead that was for the motor. I was very specific with my description as to what had happened, then surely he would have seen the output was DC, not AC?, and would have been able to assess if the board or pot was faulty.
Unfortunately he would not touch the board as he wanted a circuit diagram, so I have gone backwards really, to the tune of £88 motor, surely there are cheaper alternatives out there?

PS sorry for duplication on hmem I originally started over there and as there have been responses for courtesy Ill keep posting
John Rudd:
Paul,
