I intend on building a small robot with a DC motor that operates with voltage of 3V-6V. The website provides the no-load rpm, no-load current, stall current and torque all when it is at 3V. My first question is how can i determine this at 6V.
My second question is that from there, how do i determine the load on the motor in order to calculate if it is too much. Along with that i also need to know how to get the rpm at that load to calculate efficiency.
The motor is a TAMIYA 70167. Thanks in advance.
