Notes from the P4W project journal<br><br>Comparing HP:<br>In considering a replacement motor for the Cal 29 the amount of HP required quickly became confusing when trying to consider motor choices

Bill<br>There are so many technical issues spread across these pages, that i am trying to write a .htm listing of tutorial/technical sites and an impartial listing of suppliers of motors, controllers,

Bill,<br>Actualy any motor will act as a generator. Perminate magnet motors have the advantage in that they don't need to have the "field" energised in order to act as a generator. With out going into

Don:<br><br>I guess that I am confused. I was under the impression that only a permenent magnet(PM) motor could regenerate. Is this true or can a wound magnet motors regenerate as well? If this is the

Theres actualy a lot more to it than was previously stated. First of all the motors we are using are constant torque devises. An internal combustion engine is not. IC engines only develop torque in a

Bill in order to answer you questions it will take a lot more space than I believe this forum will allow. I will try to partialy answer them though and I am sure others may want to contribute. First

Just how many different manufacturers of PM motors in the 3-4 HP range are there out there? Do they all preform regenerative braking? (or maybe I should call it regenerative sailing?). A review of the

Simply because Electric motors HP are rated at the constant speed/load they were designed for while ICE's are rated for their peak HP.<br><br>For example some of the EV Drag racers use the ADC 9"

Anyone,<br><br>Why exactly is there a 4:1 ratio of diesel HP to electric HP? I do not quite understand why I could get by with a 10hp electric motor in lieu of a 40 hp combustion

Also, the Dayton line distributed by Grainger has up to 2-4Hp 36-48 VDC motors intended for golf carts, etc. About $800 each.

A convienient place to buy Leeson motors, I have absolutley no conection with this page or it's owners, however I do live in the state where these are made.<br><br><br><a

Bill,<br> Scott motors is part of Imperial motors. The Scott factory is in, of all places Alamagordo,NM.<br>They make permenant magnet DC motors 24-48 Volts up to and including 4 HP. They are sending

Don:<br><br>I am always seeing new things here. Tell me more about a Scott 2HP PM motor. Do they make a larger one, 3or 4 HP? <br><br>Bill

I'd try to find an old outboard lower end with a 10 x10 or 12 x 12 prop. Next I'd buy a Scott 2 HP PM motor and a curtis controller from either KTA or WildeEV or any other EV dealer. given these

I think your best option would be to look for a 45-60 pound thrust trolling motor. All of the sporting goods magazines and stores aways have sales on. You might also pick up something in the local

Changed the oil and filters in my cruising boats diesel. Normal spring maintenance. The diesel has about the same effective hp as the electric motor in my launch. I like to keep fresh filters and oil

I have a 18' pontoon boat and I'm very interested in putting together a system for use in lakes here in Ohio that don't allow gas engins. Has anyone put together a electric drive on a pontoon or can

Also keep in mind that other than the batteries the electric system will weigh a lot less than the old internal combustion system plus its fuel etc. This must also be taken into account when you

Hi Wilfred and All,<br>I think the safest thing is to remove weight from the keel (ballast) equal to the weight you add with the batteries. (to keep your waterline)Some boats do "like" to carry extra
