Re: RPM of Motors Under Load

a general definition of a motor under peak (maximum) load is pretty much holding the output shaft stationary - there are no RPM's, but the motor is drawing a ton of power trying to turn the shaft.

In order to answer your question, your best bet is to simulate what you think the maximum load would be and see what happens... Sure, there are a bunch of equations you can use (and google) regarding torque and power output, but IMO, nothing is better than a real life demonstration. In fact, today we finished one of our prototypes and tested it out with various motors to see which would work best, despite knowing that we could easily look up the specs on the motors online. The real world experience is really what gives those numbers meaning.
