Hi, I work on a project where I need 2 servomotors to be connected to a 12V battery. As the motors can not handle 12V, I need to find a regulator with a 7V output.
To be sure not to undersize this regulator I would need to know the maximum current required by the two motors.
Here are the informations I have about the motors I will have to use:
JX Servos (PDI-HV2060MG)
6V : 0.15s/60° and 48kg/cm
7.4V : 0.13s/60° and 62kg/cm
Each motor is attached to a charge (35cm*19cm and 400g). The motors and their charges will be embedded on a vehicule (from 0 to 200 km/h max) so they may be subjected to the wind force.
I read that this is possible to find the maximum current using this formula ' P = Couple * Rotation speed ' but:
- it doesn't take into account the force that will be opposed to it (the wind)
- I also read that the power up consumption might be higher that this, thus requiring a safety margin
Here are my questions:
1. How can I get the maximum current ? (I can't just measure it as I don't have access to the motors)
2. I did not choose the motors but aren't they a bit 'overkill' ? How can I calculate the couple I need ?
3. Will a motor with a lower max couple consum the same current as these 60kg motors while the max couple is not reached ?
Please, try to explain like I'm 5 years old, I am a beginner Thank you
