    Question about torque through a differential.

    ...it was definitely a long journey, but I think I finally got there. Thanks for all the help!

    Question about torque through a differential.

    Tmoose -- no, these are DC servo motors. Lionel -- OK, torque must be equal on both inputs. That being true, how could you have a torque higher than the rated torque of a motor on one side? Wouldn't the whole system be reduced to the max output of 2X the smallest motor? In other words, in both...

    Question about torque through a differential.

    First of all, thanks for all your help and taking the time to fully explain this. I really appreciate it. What I meant by THIS case is that because both motors happen to be the same, the ratio ends up being 2:1. But this isn't necessarily the case for all situations. For example (assuming I'm...

    Question about torque through a differential.

    Lionel, OK, so in THIS case it would act as a 2:1 reduction. If, for example, the motors were not identical (T1 does not equal T2), then the reduction ratio would depend on the ratio of the motor sizes, correct? I think the confusion for me from the beginning was that I was being told a...

    Question about torque through a differential.

    Lionel, If I understand you, you are saying that if one motor is stopped, the other motor will see no load change? My current design is using two electric motors on a 24V power supply that is restricted to a maximum of 2 amps. So based on your example above, I would not have to size one motor...

    Question about torque through a differential.

    Actually, if one motor locks up, the output speed would be cut in half -- not doubled. As far as the torque goes, the output torque would remain constant, however, the load on the motor that is still operational would double. Which would also be true for any portion of the gearbox that is tied...

    Question about torque through a differential.

    Yes, both motors have brakes to prevent any back spinning. That is exactly what I was always taught. I just wanted to verify that I hadn't forget any fundamentals of differential design. Thanks!

    Question about torque through a differential.

    I've currently got a gearbox that is driven by two electric motors. Each motor is ran through the same differential such that if one motor were to fail, the other motor could still drive the system. My question is: Will the differential act as a torque multiplier? I tend to think of it like a...
