I am a software engineering major, and I am having some trouble with an electric circuit in my satellite project.
Basically I am trying to generate 1G on the inner surface of a cylinder with a radius of 0.03m, connected to an electric motor which has to rotate at about 173 rpm (to generate 1G on a 0.03m cylinder) according to my calculations.
In the circuit I need to connect obviously a battery to the motor, and regulate the rpm with a microcontroller (like an arduino). So I need a part or a circuit that will allow me to control the voltage via the microcontroller, to increase or decrease the rpm of the motor. Since all batteries are DC I guess it is preferred that the motor will be DC as well.
This is an approximate of the general circuit I imagine (http://s10.postimg.org/pibf3x2fd/satellite_circuit.jpg).
I just need the part or a circuit that will allow me to control the voltage via the the microcontroller.
Thanks for any help
