Need information about this Motor ?

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.

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.
