The right answer is to use a 48 volt battery pack and 48 volt motor controller and run the motor controller throttled at no more than 36v. The...
I measured the KE (rpm) with the prop in air and the load reduced the rpm some but I am glad they almost agree. The resistance measurement with a...
Initial load tests Based on my locked rotor current and torque tests, we are looking at a KT of 18 oz-in/A. This is better than I thought but...
No Load curve Here is the measured no load speed vs voltage of the 36 V trolling motor. I pushed it to 50 volts with no issues. I know the...
Series motor curves I attached the performance curve for one of my series (forklift pump) motors. Notice on the attachment the rpm rises rapidly...
A series wound(field) DC motor will overspeed without load. An unloaded PMDC motor will stop accelerating when the rpm approaches the back emf....
Hp curve I atached a typical DC motor curve for hp vs torque and current. This is from electric motor I used in the electric conversion of my...
If you throttle the controller so the average dc voltage is 36, the motor should draw about the same current if you applied 36vdc. I'm not sure...
Sorry, I didn't answer your questions. My questions are: Is this a real possibility? Yes. You can do it. If so, can you push the...
Trolling Motors I have upped the voltage in trolling motors before and I am upgrading a 36 volt unit now. I have two 24 volt models that I run...
hull Look at the picture in my profile. My wooden row boat is/was about 200lbs empty and a little over 12' at the water line. The 'square...
The transom is Out of the equation when you raise it out of the water. At least that's what I found out by shifting my weight forward in my...
Check EBAY. See these props on there from time to time.
Go pure battery... The A123 prismatic cells are now becoming more available. For they run about $32 US and have a 20 AH rating. For the weight...
Alpha drive A buddy has an alpha drive like yours. The leading edge of the lower vertical section has a small hole which clogs up. It might...
