Hello, I hope you are all well.
I have come to a little bit of an issue on my project which uses a 12V BLDC Motor Rated at 4A. The problem is, that the voltage rail of which the motor is connected to can vary from 11V - 24V.
I need the motor speed to be with 11-12V and not to speed up over 12V. The reason being it used for suction and if I keep it between 11-12V then I have a reasonably tight tolerance of the suction and flow rates.
I understand the availability of DC-DC converters such as buck, Buck-boost and regulators. But what would be the most efficient option to use, as my power supply and or battery can at most supply up to 4.5 A. Also taking into consideration EM interference (this is for medical application but I really can't go any further by saying what the application is for)?
I would really appreciate help on figuring out the best method of stopping the voltage supply to the motor from going any further over 12V (going down is fine).
Sorry, its a bit vague, I will try to answer as much as I can with without giving away sensitive information.
I hope to hear from you guys soon
