I am confused about how you can tell the amperage and voltage a speed controller andan electric motor can handle??
can I tell with a volt/amperage/ or ohm meter
I know think you can tell if the electric motor is being over worked by the heat it gives off =
1. If it is hot to the touch it will burn out soon!!!!
2. If it is warm like a baby's bottle it will probably run indefinitely as long as the voltage does not drop more than 10 % ???? of the motor design ????
electricity was not one of my post graduate studies I am useing a 48 volt lithium battery system on a 48 v golf cart 7.5 hp motor
in a 10,500 lbs 30 ft colombia sailboat.

Subject: [Electric Boats] Speed controllers. Cheap or not....
I am working up plans to convert my 22 ft daysailer to electric and I'm looking to do it as economically as possible (OK, I'm a cheapskate). I have noticed that there are motor controllers out there running everywhere from about 35 bucks for a 1000W 36V controller advertised for e-scooters up to more than 500 bucks for a top end model that will probably make my coffee in the morning. I looking at using a manta motor with 36V power. What advice do you all have out there that will keep me from making a costly (or cheap, as the case may be) mistake.
