hi I am not very smart .. lol I may be in over my head ..
I want to build an electric motor controller but only as an amp protection and need some guidance ..
most large DC motors require controller that at bare minimum have an voltage control to keep the DC battery supply from having to many amps pulled ..(this may not be the correct terminology) sorry.
what I am wanting to do is get a better understanding of some components used in most controllers ..
I will give you what my project is and why it is not available on the market .
I will give you a scaled down version of my project .. After I finally get a grasp on the blue brint I can scale it up.
A 12v DC battery hooked directly to an electric fan for example .. I want the fan to pull all the amps it needs unless it is under extreme load .. under to much load it will pull to many amps from the battery .. I want it to have the maximum volts available but I need some way to regulate the maximum amps to the fan so I do not short circuit the max amp rating on the Battery.
The problem is that many dc controllers are very complex and have speed (voltage control) and motor startup settings .. I need to design a simple control that all it does is give a non-adjustable amp current protection ..
help me understand MOSFETs in parallel for first order of business . I do not need the home built amp protection to communicate with the motor
