    Hi All

    I have a duff motor/actuator on a reclining chair. In the last century, backstreet wizards changed brushes/did rewinds etc- I recall someone doing my washer motor...

    Do people do that any more? Ideas for who to search for. Appliance fixers?

    Ideas welcome. Ta

    I remember rewinding 24 volt wiper motors late 80's but even then it was not economical to do it, it was only done as new was not available. If you consider £25 an hour, and it could take 2 hours to rewind plus another hour to dismantle and rebuild, plus materials used so looking at £100 and at that likely not well balanced, so in the main need new.

    Try your local disability shop or wheelchair shop. Chances are they'll either know someone who does or who can provide a used replacement

    The last time I looked at the cost of rewinding, it was more expensive than buying a new motor.

    Charliegolf, do you know what's actually wrong with it?

    No, only that it's not working. I'm fairly confident that it's not the switch or the power supply, cos I successfully worked the other chair using those components on the duff chair.

    Unless it's a very expensive motor (many £100s absolute minimum) then a new motor is the only economic option.

    Actually, replacing the bushes may be a far cheaper solution and all that is needed.
    Charlie, can you see if the bushes are replaceable?
    Can you provide a good quality photo of the motor? has it a plate or sticker on it giving it's details?
    Can you see the end of the bush holders either side, do they look removable?

    A new set of bushes may only cost a few quid.

    Obviously the brushes will be the cheapest option if that is the cause, anything more than that then a new/refurbished unit is the only other option.

    Regarding rewinding motors, when I started as an apprentice we used to hand wind small things like drill/food mixer armatures and field coils. By the time I finished in the trade a few years ago it was far cheaper to replace anything from 11kw or below unless it was a specialist motor. Anything single phase was simply replaced.
