Does anyone have actual measured data for CIM no-load current (and no-load rpm) vs applied voltage?
I know that the motor curve spreadsheet
here just scales it down linearly, but I've seen other sources that indicate no-load torque (and thus no-load current) of DC motors is a function of the square of the speed, or somewhere in-between square and linear.
And yes, I realize this is a very small current and it can safely be assumed to be a linear function of applied voltage for all practical applications for FRC, but I'm interested in the nuances.
Thanks.
