Carbon Brushes... |
[Down to Last] |  |

OK, I know how carbon brushes work and that they wear down, but my question is how quickly ?
I know it is probably in the same league as "how long is a piece of string ?" but if anybody could help inform me I'd be grateful. For example, do certain things make them wear down quicker ? And under well maintained circumstances do they even wear at all ? Also, what are the early symptoms of worn brushes ? I know nothing other than the role they play in the motor, so any information would be greatly appreciated. | ||

 How quickly the carbon brushes burn down depends on how often or how much you use the vacuum cleaner, if you had a vacuum cleaner that had 1cm long carbon brushes that had worn down over time, that could last you a year, on average use, but again it depends if you vacuum daily, weekly, and how many hours you vacuum for. I am not aware there are any specific symptoms of carbon brushes wearing out, however, I do know that if one, or both of the carbon brushes are worn down too much, resulting in them not contacting the comutatuor propperly, the vacuum will cut out and therefore will not work until they are replaced. | ||

Well I'm pretty lucky then!
I have two vacuums which are older than 30 years - my 1977 Hoover Senior and my 1951 Hoover Dustette. Both of which still run like brand new with no repairs what so ever in their lives, as do all my other Vacuum Cleaners. The reason I believe they do so is because I don't use too low a height setting (where applicable), don't block the air ways, change the bag before it gets past half full and keep the filters spotless. | ||

I totally agree Benny, those 600W motors are truly brilliant.
I know I shouldn't jinx it, but I don't believe my 1977 Senior will ever die, at least not through motor problems. Although you say the motors never broke down, did you ever have to replace the motor brushes in those or were they pretty much everlasting on those old dirty fans ? | ||

Did you ever use a commutator stone to seat the brushes like some people say you should ?
On that subject, do you know where I could buy replacement brushes for the Turbopower 2 motors ? I don't need any just now but for future reference I decided to try and find a source but cannot find a single one! | ||

No, never. I never saw one with a burnt out motor either. The motors were very good. Electrolux of the same period was another matter altogether. | ||
