thanks alot skimask for your interesting information, I learn new things about open differential , I read it but I can't distinguish between straight and turn mechanisms and what happened and what is the thing make this machanisms straight or turn.

It is a bit difficult to picture without actually seeing it in operation.Originally Posted by iugmoh
Take the gear case cover off if you can, turn it and play with it.
As soon as you see it in operation, it'll all make sense...(or maybe go to an auto mechanic shop and see if they've got one to show you or something)
EDIT: I just took another look at the pictures in post #1. An open diff is exactly what it looks like to me. The motor input is slightly offset from center, the round bump on the one side is for the large bevel/ring gear, probably driven off a center mounted reduction gear setup, the spiders and side gear are probably mounted in the middle.
You never did mention exactly what this motor was from. I could be a wheelchair setup as long as it has a sort separate steering motor, unless the brakes actually accomplish the steering.

motor
some motors, ac and dc have little thermal switches in them that open when the motor gets too hot so people don't burn up.

Picture 2 half circles, for instance #1 having a radias of 500mm and #2 having a radias of 400mm, and both having the same exact center. now imagine those 2 half circles represent the tracks left by the wheels. the inner wheel travels a shorter distance than the outer wheel does. That is the purpose of the "open differential" . Does your motor have 1 set of 2 or 2 sets of 2 brushes? BTW a brushed motor is commonly referred to as a Universal motor as it can operate from A/C or D/C.

I don't believe that statement is entirely accurate.
Take one of those little hobby motors for R/C cars...
Put A/C on one of those and it'll just sit there a jiggle...depending on the A/C frequency of course...and the voltage...as stated above it could become a backlight...and a short term heater...and possibly a insect defogger...or get rid of annoying kids...

I should have excluded PM motors from that statement as ski pointed out make good space heaters on A/C.

In an automotive differential, you have 4 pinions or "spider gears" 2 of which are attached to either axle. the other two are driven by the carrier through the common shaft which goes through the carrier. The carrier is driven by an attached Ring and Pinion set which allows for a 90 degree change in direction of power. the 4 pinions or spider gears are in constant mesh and as the assembly is rotated by the carrier around the axles axis, it allows the axles to turn at a constantly changing ratio from zero difference to 100% difference depending upon the load applied to each. If one wheel loses traction that wheel will spin wildly, while the other wheel remains motionless.

Clear as MUD!
Technically accurate description, just a pain to visualize...

thanks for all, all things about my dc motor is now clear , the other two wires are for thermal protection , and in this motor you can't control speed of each wheel alone electrically, but there are hand break near each wheel which you can use to slow one wheel to steering the motor to other direction.

The 2 extra wires actually connect directly to the Turbo-Encabulator...

I have this question ?
Is't possible to run a series wound motor as separately excited or shunt excited motor ? by applying for example a dc voltage on field coil to be separatley excited , or it's designing to work for specific type ?
|
I do not think it would run. Something tells me that if it would run, you would not have much power.
Map out the coils, a certain type from different manufactures may be able to be modified differently.
Sorry for the vague answer.
