The motor delivers between 10 to 15W, uses 6V and stall current is 4A
If you could find a good datasheet or your motors, we could answer your question real fast . . . but I doubt they exist . . .
So if a motor requires 6A to run but your batteries can only apply 4A, they the motors will just operate at a lower torque. This lower torque may be acceptable to you, in which case there will be no problem.
Does this also apply to stall currents?
Then my motor stalls, and asks 16A, but my batteries can and will only give their maximum, being 5A (just a guess). This will cause the motor to have little torque at that time.
You should calculate how much torque your motor will need, and find out how much torque your motor can supply, before being concerned with the motor stalling . . .This page can help:http://www.societyofrobots.com/mechanics_statics.shtmlhttp://www.societyofrobots.com/mechanics_dynamics.shtml
If your motor stalls, then this means your motor isnt strong enough. You dont want to run your motor at stall current. Bad things will happen.
So my motors won't run at stall current and bad things won't happen. Right?
All I need to know is, what are the typical current values for NiMh batteries?*Max continous current? ( 1 x Capacity , or maybe 3 x C , ... ?)*Max peak current? (for a short time)
