Hi Billblack, yes it's something similar. No motor is not getting hot. I've taken apart the puller and finds the motor can run on either 12v or 24v. I'm going to try running it on 24v see if it works better. If not I've been exploring possibility of using treadmill motors but I'm kind of...

I see. So instead of drawing from battery. May be I should consider drawing directly from alternator? ps battery is located underdeck of my boat. So no moving air. But it's not hot either. About 12 degrees C. One more thing, would parallel linked 2 batteries output 50amps each and I...

Hi Stewartct, you water current and drag is a big problem. Hi Mech Engineer. I've just found more info on the battery. Cranking power 750amp, Amp Hour Capacity: 103 Reserve Capacity: 205min. Is there a way of calculating usage length from Amp hour capacity? Oh the draw is about 100amps...

Just to post new find. I've found winch motors Ramsey winch motor. It runs on 12v. I'm thinking maybe the REP8000 or REP8.5E motor. At 2000lb load amp draw is 168 and 110 respectively. I'll only be pulling 300lb (500lb max) I figure with Nautilus Deep Cycle Battery 750amp crank power and 205...

What I'm trying to do is get a more powerful crab/prawn puller, without going into hydraulic. Right now I have a line hauler which is only 1.4 hp running on 12VDC. Its speed when running again current and with weighted trap is just now fast enough. It's rating is suppose to be 110ft/min with...

Mmmm, okay I don't know how to do the calculation. But judging from what you wrote, I'll say that is not the right choice?

Hi, can I connect two 12v batteries in series to get 24v and also each battery has individual connectors connected to 12v alternator from engine for charging? Would this cause problem? Or what type of converter (if there is one) that can do 12v to 24v with max. 50amp. Another option I...

I've search on Google and came across these motors. http://www.robotbooks.com/robot-motors.htm Seems like a good choice. 4.5 hp powered by 24Volts. Or did I miss something?

I'm looking for 12 VDC (preferred) or 24 VDC electric motor that can output >2hp (preferred 3hp) and with gear reduction to 100~150 rpm. I've looked every where but has no luck. Can anyone help? Thank you.
