Does anyone know the start up energy for the motors?

When I tested these it was 2.75 amps stall current at 3 Volts. The resistance is 0.9 ohm. Stall current = ohm * voltage. At 6 volts the stall current is 5.4 amps. Free running, no load will be a lot less. Something like 75 milliamperes.

No. They are 15000 rpm at rated voltage

I've looked at all questions and find the answers to torque,operating current at 3V no load, and stall current at 3V questionable. What is the values?

Not sure why these numbers are important to you, so answering them leads to a lot of "depends." The no load 3v current depends on how warm the motor is cold motor is 0.9A, a hot motor is 0.65A. stall current depends a lot on the power source a chemical source (battery) vs a rectified source vs a pulsed (DC-DC) source; I can get between 1.2A and 3.7A. Torque is also highly dependent on power source and age of the motor (they wear out fast)
