As usual these day when something breaks and is going to be binned I ask for it take it apart and see what i can save.
This is what I found in the last one would like to know what it al is.

The two things with red-oxide-coloured parts look like AC electric motors.
-
two motors Ac 230v 50hz. from what I can read upside down, circuit control board, with surfacemount powertrans former(blue box) Larger one on the right looks to have gear reduction mechanism on the end of the motor. the red handle thing looks to be a screw driver.
the on off button the green box with the spring on the button looks to be a latching button. and then you have a gear drive mounting plate.
Wouls have been a help if you would have mentioned what it came out of. If you still have the make model and brand you can look up on the web for parts lists or manuals and find out more on the motors if they have names or other identifiers. :ddb:

They might be solenoids...?

Google the visible number on the smaller one - EM2513-125

They might be, they do seem to have an output shaft though. Still, they could be rotary solenoids, we used to call them 'Ledex' motors, usually had some sort of solenoid actuated ratchet and would rotate the output shaft one step for every input pulse. I guess their function has been taken over in a lot of applications by steppers, but steppers require more control circuitry.

Perhaps :scratch: the blue box is a relay. And there's definitely a screwdriver in there ::)

PT seems bang on
Looks like two shaded pole motors, rh one with a reduction gearbox.
These things often normally run hot BTW, don't like 'em much.
Blue box thing is almost certainly an encapsulated transformer, it's near two black electrolytic capacitors, and the little square thing in front of the caps. could be a sil bridge rectifier, these bits are usually fairly close together as a PSU. A better pic. of the inscription will probably tell what the ac output is.
Usually load volts and VA rating.
What the black thing is with a gear on it is anyones guess from the pic. May just have a pancake motor on it. Speculation .. ::)

Should have explained a bit more
This is(WAS) a silicone putty mixer only outer casing broken
The small AC motor turned a small gear that turner the thing with the big gear ( big gear has a big magnet inbedded) and then i opened some bits to allow you to see in side.

Blue bit looks like a PSU 24v ????? both motors sais 230V
(http://i608.photobucket.com/albums/tt161/geroli/DSC_0016.jpg)
The bigger motor just spun the mixer
(http://i608.photobucket.com/albums/tt161/geroli/DSC_0017.jpg)
The smaller of the motors pushed the putty out slowly with a chain drive from that thing in first pic.
Is any of this usefull (remember im eletronically dislecsic!!!)

PSU is 24V @ 1.25A .. tranny will be higher volts output with no load.
It may well be the shaded pole motors are not rated for continuous use. Often, if they are a stock motor, this will be stated on motor. But, if they are made for the device specifically, it probably wont. Look for 'duty cycle' 'duty ratio' or similar.
Magnetic clutch looks handy, I would guess that probably works off the 24V ish DC ..
