<div>Kieth,</div><div>I have an extra 36v golf cart motor here, but there are two problems ,I think, anyways. My understanding is, for a dc motor to work as a generator it must have permanent magnets, I think? The next problem is the sheer size and weight. these motors are quite heavy, witch is probably why they are so robust. If it did work, it would be very tough and reliable.</div><div>Hank</div><div><br></div>

<div>Brian, </div><div>On 24v the motor takes 70A so at 36v it should be around 50A so I don't think a charger will do it. I like your AC motor idea, except that I intend to switch over to AGM when I dive and will drive the sub with the main motor. I have to give it to the Nekton engineers, that drive with a rudder, really works well. The addition of positioning thrusters up front will be perfect. It would be different if I didn't use gamma as a boat and sub all in one. I sure like your idea! I am going to see if I can find a 3hp universal AC\DC motor.</div><div>Hank</div><div><br clear="none"></div>

But there may be a duty cycle issue running a charger for that purpose may shorten it's life. What about just running a AC motor off of a regular AC generator for the sole purpose of getting across the lake? </div><div> </div><div>Brian<br clear="none"><br clear="none">--- personal_submersibles@psubs.org wrote:<br clear="none"><br clear="none">From: hank pronk via Personal_Submersibles <personal_submersibles@psubs.org><br clear="none">To: Brian Cox via Personal_Submersibles <personal_submersibles@psubs.org><br clear="none">Subject: Re: [PSUBS-MAILIST] 36v alternator<br clear="none">Date: Mon, 16 Oct 2017 23:09:44 +0000 (UTC)<br clear="none"><br clear="none"></div><div class="yiv2087218417yqt8488619247" id="yiv2087218417yqt81596"><div style="font-family:Helvetica Neue, Helvetica, Arial, sans-serif;font-size:13px;"><div></div>
<div>Brian, I don't have a 36v charger. I charge my bank 12v at a time.</div><div>Hank</div><div><br clear="none"></div>

I am installing the original 2hp drive in the escape pod with the jettisoning prop assembly. I will feed the 2 hp 24v motor with 36v so it will be 3hp. The motor is rated at 3hp 36v. I will run a power cable from the generator to 3 12v batteries in the pod, and I will travel on that power. When I dive I will switch to my 36v agm bank. That should work since I am towing the tender anyways. I am having trouble finding a 36v alternator. I want an alternator with internal regulator. I guess in a pinch I can use 3 12v alternators but then it is not compact anymore. Any ideas?</div><div>Hank </div></div></div>_______________________________________________
