Motors in Breadmakers?

[greencardigan]

Hi,

What sort of motors do most breadmakers use?

Voltage?
Current draw?

Im planning to strip a BM down and use the parts for a custom made roaster.

Re: Motors in Breadmakers?

Capacitor Start/Run
240V AC
50Hz
300W and up

How are you planning to use the motor gc?

Re: Motors in Breadmakers?

I havent decided exactly what my new roaster will be but Im thinking something like a large scale version of a hot air popper. The BM motor would be used to agitate beans.

Rightio gc....

Please ensure that you have your completed "Fluid Bed" Roaster inspected and tested by a Licensed Sparky before plugging in and powering up, wont you? Wed hate to have one of our fellow CSers injured, or even worse....

Cheers,
Mal.

Hi GC,

Ive cooked 2 BM motors to date, so currently use a 12v PC fan to cool my BM motors.
For a custom stirrer, I think that unless you have OK gearing for your stirrer paddle if not optimum or you have a variable speed gear box or similar, then I would try a 12VDC windscreen wiper motor which should be more easily speed regulated.
Also 12VDC is not the dangerous monster 230VAC can be.

Just a thought

I have been using a BM motor for my KK Turbo roaster for 18 months no wories but thats the hole base with belt drive..As Mal said make sure that you have a sparkie wire and test...

Adding to the above
A KKTO was conceived to be used with 2 heat sources (1) Turbo Oven & (2) Heat gun

The base hub can be inverted and many different small 12V motors can be used

So it can be a basis or starting point for many designs for which I have 20 + versions

Re: Motors in Breadmakers?

Ok thanks for the comments and suggestions.

I thought the BM motor might have been DC so I prob wont use it.

I like the fluid bed idea but will need an agitator as the HG wont provide enough air volume.

Id head down the Corretto path but Id like a more elegant looking setup. Also Id prefer to be able to cool the beans in the roaster.

Have a look at Oatley Electronics out of Perth for a source of DC motors and controllers.

Either that or get hold of an old R/C car and strip it of some parts might work for you. The 540 Mabuschi can size (used in these) is good for around 200W of good life at 10-12 V

Re: Motors in Breadmakers?

I already have a small geared DC motor i can probably use. Im just wondering how it will handle the heat.

Re: Motors in Breadmakers?

Extend the shaft and place something non heat conducting between the gearhead and oven area/agitator blade.

There is some pics around somewhere I will see what I can turn up

Re: Motors in Breadmakers?

The use of a 12-24V DC motor seconded from a windscreen-wiper mechanism (or similar) would certainly be a much safer way to go, with the added bonus of almost infinite speed/torque control (depending on the controller used) - Ideal for a prototypical design... 8-)

Thanks, some pics would be handy

Pretty sure Ive seen someone use a length of 12-13mm O.D. Bamboo for this purpose with a suitable drive socket/shaft fixed to either end. Reckon that would work pretty well....

Thats the one I was thinking of, couldnt find a pic. Using a socket (attach the agitator to this) and socket drive extension as part of your design makes for easier removal of the roast chamber.
