Homemade tumbler motor help

[abunaitoo]

I'm trying to make a rotory tumbler.
I have a motor from a Bosch washing machine.
Can't find the wiring diagram.
Someone know anything about these motors????

There are 5 blue wires and one white wire in a gang plug.
The white wire is a grounding wire.
It looks like two of the blue wires from the gang plug attach to, what looks like, a speed sensor on the rear of the motor.
The other three go into the motor body.
This was a 110v washing machine.

I think if I can get this motor to work, it would make a great tumbler motor.

Is the white wire attached to the frame of the motor?

Do you have a multimeter that you can run a resistance check on the motor leads?

Is this what your motor looks like? Note "speed sensor" on motor endbell.

If it is an ecm motor, they are very high dollar motors. Not going to go into an explanation here / now, but if it is, they are specialized for their application. Not to say you can't use it to build a tumbler. I'm subscribed to this thread.

treadmill motor works better

treadmill motor works better

+1 find an old treadmill by the side of the road that someone finally realized they are not going to use. Take the long belt off and shorten the bed to accommodate your drum so it fits between the rollers. You will have a variable speed tumbler with minimal fuss.

The wash machine motor will require a great deal of speed reduction to keep your drum from going in to orbit. The treadmill setup has all the speed reduction and control you need built in.

Picture of a tumbler I made 35 years ago from a scrapped furnace blower motor and pulleys from a 1960's to early 70's clothes dryer. Drum is plywood, can tumble large amounts of brass in a hurry with corn cob media with some liquid car scratch remover added.

Like this:


and you can take your pulse while you tumble too...

Thanks for all the help.
I've posted so photos.
I've never seen a motor with this kind of wiring before.

There are six wires. Five blue and one white.
I checked the resistance between the wires.
First three are seperate from the last two.
Last two go to, what I think, is a speed sensor on the back of the motor.
First three have the same resistance in any combination.
White is attached to the body. To me, it's the ground.

I have a few treadmill motors, but there being reserved for my drill press, band saw and lathe.
Always on the lookout for more on trash days.
So many projects, so little time.

If it was 240v, then the three wires would make sense. However, since it is 110v that seems kind of odd. Maybe the three wires are for a sensor and the two in the back are for power. Have you tested those two?

[leadman]

The motor is probably at least a 2 speed, more likely 3 speed so this would account for the extra wires.

Google is your friend.

Here's a reference to what the six wires are:

Scroll down to the next to last post...........

"The 6 leads (starting from the 2 thinnest wires) are: 1 & 2 tacho generator - 3 & 4 armature circuit - 5 & 6 field winding. The problem being that it is impossible to know the correct orientation of the field winding in relation to the armature circuit. If either gets swapped around the direction of rotation changes, which may cause problems."

Washing machine motor (upright) has to be at least two speed (wash and spin) and reversable (back and forth wash cycle) along with some sophisticated electronic controls. If it had a delicate cycle then a three speed motor would be required. How much of this do you need for a tumbler? Can you disconnect everything except "go" and use mechanical (pully) speed reduction?

[abunaitoo]

With the great help from jsizemore I got the motor to work.
Ununfortunately I failed to notice that it didn't have an internal fan.
Not sutable for my tumbler plans.

The white is the ground.
The two last wires are for the speed sensor.
The last three wires are used in different combinations to get different speeds and reverse.

Thanks for all the help.
I'm going to start looking for another free treadmill.

I recovered a motor from an old dryer and it works perfectly. Also an old furnace motor works fine, just have to play with the size of the pulleys for the proper speed of the drum that is turning. As other posters have mentioned a great source is treadmill motors, they can be adjusted very easily for speed.
