    Total torque of a multi motor system

    Sir, I realize my questions may seem rather remedial to you guys, but there is a reason why I am asking them. More often than not, the question is a rhetorical question and I just need validation of my presumption. I value y'all's opinion tremendously. That's why I continue to post questions...

    Total torque of a multi motor system

    No offense, berkman, but I can always count on you to be the Negative Nancy when I ask any sort of question. That being said, there are several differences; consequently, the most notable of which is this particular question dealt with overall power, not efficiency. It also did not utilize any...

    Total torque of a multi motor system

    So I have four motors, each capable of producing 1 newton meters of torque. They are all running into a singular drive axle at 90degree offsets. There's no gearbox exchange or power transfer medium. It's axle to axle engagement with a pinon gear. Disregarding any sort of losses that may be...

    Estimating efficiency of a system

    Also, I don't know what you were referring to in terms of trick somewhere. Consequently I don't know which chart you are referring to, but there's all kinds of noise in that chart that I posted.. Thank you Mr Jack action. This question, although it has become quite convoluted in more difficult...

    Estimating efficiency of a system

    I am pushing this motor beyond it's normal operating range. I get it. However, this is all they gave me to work with on this preliminary design. It's a proof of concept to justify investing more money to get the proper motors paid for and installed. The proper motors for this configuration will...

    Estimating efficiency of a system

    Here's the full report. Please see attached. The data points that are illustrated on the second page are just the first few seconds of the test. The entire file included thousands of data points over 200 seconds.

    I label the Matlab data here so you can see what I was getting from the digital torque transducer

    Estimating efficiency of a system

    And for the record, I never said it was strictly theoretical or strictly real motor data. It's both. I have a known set of established values that I've came up with using highly precise scientific instruments, and I'm wanting to know if I can presume certain facts to get in essence get a...
