I need to find a way to control the speed of an electric motor over a wide rpm range so that it is what I want it to be, per it's input w/o feedback. This would be a small motor, like an RC car type. I want to write a number to a DAC and either use a Voltage source or a Current source as the controll, but need to be able to lock the speed over a wide rpm range with a lightly varying load, ie: load will vary with rpm, pretty linearly, and be light in comparison with the torque capability of the motor, and needs to work with many motors ie: for production in a product. Any help? thanks,, C. Speed is going to be up near 7000 rpm at the top end, aroud 200 at the bottom.
