Hey everyone,
I am a Mechanical Engineer by trade so this whole electronics world usually doesn't go over too well with me. I have been scratching my head as to how exactly I can control the propeller direction and speed of my trolling motor.
The model is a Minn Kota 55lb Thrust Endura trolling motor that runs at 12V with around a 55W load at full throttle, which means around 4.6A of current if I am not mistaken.
It broke recently and I have taken it upon myself to come up with a better solution to regulate the speed so it is infinitely adjustable from 0% to 100% and not five different set speeds.
I was thinking of using a DPDT switch wired so that it will reverse the polarity, F-Off-R, but I am having trouble finding the right device to regulate the voltage so I can slow it down. I was thinking of using a potentiometer but I cannot find one rated high enough, thought about using a house dimmer switch but I guess that won't work, a rheostat but I can't find one that will work correctly, and finally an infinite switch such as one used in an electric stove range.
I have no idea what device to use to lower the voltage and how to wire it, so I am hoping some members here can help me out!
And as a side question:
At 12V, 55W, 4.6A does that mean a resistor with a 3ohm value will drop the voltage enough to stop the motor? It should be able to drop it just shy of 14V I think.
Thanks for any and all help!
