cement mixer rotates too fast

[Jimk]

No.

You need thread reading glasses.

[Jimk]

Or you show us just one example....

just bought a second hand belle 130 cement mixer. to find out it rotates so quick it is dangerous and pretty useless. if i changed the capacitor would it resolve the issue. should i change the complete motor. feel stupid and lost money .....any advise appreciated

[John Rumm]

No, the cap has no effect on the motor speed.

What speed is it rotating at (should be about 15 rpm or 4 secs for a single complete rotation)?

Is it the original motor?

You might be able to change the size of one of the pulleys to get a different gearing.

You can see what size it is originally supplied with:

show us the mechanism & motor so we can see what's wrong.

I'd have asked exactly where it was made and what for exactly. Is it an induction motor or a brushed on. There may well be some wiring that is configured for the motor which is wrong. Seems a little odd to me if its as new.

More likely a new, and incorrect motor pulley or something like that, I'd have thought. Brian

Yes and not on home owners clubs web site, use a cloud service for the picture and post the link to this thread. Brian

the makers spec* is 26.5 rpm so count how many revolutions yours does in a minute and compare

Three thoughts:

1. Change the motor pulley for a smaller one or the drum pulley for a larger one.
2. Check the motor speed on the rating plate, it should probably be

1425'ish RPM but perhaps someone has replaced the motor with a 2800'ish RPM motor.

1. Sell it and buy another

Is it 110V being used on 230V mains ? :-)

[John Rumm]

To be fair - if that is right it does seem a bit fast compared to most.

[harry]

There's only one possibility. Someone has fitted the wrong motor. It's an induction motor, the smaller ones commonly run at either 1480 rpm or 2800rpm. (ish, ie a bit less than synchronous). They come in standard sizes/frames/shaft diameters

BTW make sure the gearbox has oil, they don't last two minutes without. If there's a lot of play in the gearbox, (twiddle the drum) may not be worth repairing.

[tabbypurr]

or the wrong pulleys.

[Robin]

or that it's rotating at the designed speed but that's faster than the average

[tabbypurr]

or that it has the right motor & right pulleys but that the centrifugal speed regulator is not working. (More likely to apply to historic equipment.)

[harry]

There is no such thing on an electric cement mixer.

[ARW]

Just stick the Benny Hill theme tune on and work a bit faster.

[newshound]

Belle 130, I think you mean the wrong gearbox. Perhaps no gearbox?

[newshound]

No, should just be an ordinary induction motor, probably 1500 rpm, AND A GEARBOX.

[tabbypurr]

If you can show us the speed determining mechanism on every electric cement mixer ever made I might believe you.
