Re: Why have my magnets come unglued? Perm 132 motor

We are running the motor at 72 V and max 200A. According to most sources that is within the range of this motor however I have seen one German seller saying that it only goes to 60 V. I am uploading a few pictures. My current plan is to try to remove the remaining two magnets then reglue all eight o...

Why have my magnets come unglued? Perm 132 motor

Hello all, I have a perm 132 motor in a custom ATV build. We recently disassembled everything to paint the frame and we put everything back together and we went to turn the motor and it sounded like there were rocks in it! There were also some strange things happening with the electronics before we ...

Looking for temp sensor for perm 132 motor

Does anyone have experience installing a temperature sensor on a perm 132 motor? I want to tow my friend up the local mountain here and I don't want to kill my rig. Anyone know what temperature would be considered too hot? I have a cycle analyst V2.3 and was dissapointed to learn the V3 has temperat...

Re: Legal classification of my custom build - Quadricycle? ATV? Wheelchair? All?

Just logged in after a long while. Thank you all for the thoughtful responses especially wturber. I've ridden it around a bit in Pacifica, CA and haven't had any issues yet. I've gone right by a cop on the road and he didn't even look twice. I think it is an electric ATV but I am most certainly call...

Quality of Kelly Controllers

Hi all. I have an electric ATV off road wheelchair thing I'm building and I am using a Perm 132 motor and an alltrax SR72300 controller. I was advised by the guy at the local EV supply shop to stay away from the Kelly controller I had purchased and his reasoning was that they tend to fail under high...

Legal classification of my custom build - Quadricycle? ATV? Wheelchair? All?

Hey all. I have built a custom vehicle that doesn't really fit into one legal category. I'm looking for help finding the laws regarding this. It is a pure electric full suspension vehicle with a perm 132. It is very fast but we've installed a speed dial so we can dial the power back. I think this wo...

Ebike Battery Cell Layout Questions

Hello ebike battery builders. I am going to try making my own battery packs for fun and to save money this time around for my electric atv project. I bought some batteries from Em3ev a few years ago and I want to use the same form factor as those. The packs are 5s20p. So 72V. At first I tried puttin...

Re: Should I use Cycle Analyst on my build? - Wiring

Thanks guys I agree- It would be great to hookup the throttle but the throttle is resistive 0-5k ohm. The CA wants a 0-5 volt throttle. We have a lot of time into integrating this into the hand controls. Unless someone can think of a way to inverse the voltage output on the throttle...

After thinking about it more I think the 72V controller is the way to go. Thanks

72 to 52V DC DC converter - Do they exist?

Hey All, So I built an electric quad using the motor and controller from a 2010 Zero motorcycle. The motor is a perm 132 and the controller is an alltrax that can take 52V. Thing is I spent $1200 on 72V batteries already because I thought I would be using a different controller. My question: Can I b...

John, that is interesting about the efficiency number crunching. I wonder how they are even measuring torque with a propeller on it... isn't torque and power usually calculated by accelerating a mass?

This is theoretical for now and cost prohibitive but... If I were to want to use this motor: http://store-en.tmotor.com/goods.php?id=891 on a go kart... what controller would I use first of all. Would I need the esc? I'm unfamiliar with the drone world. Any other problems I wold run into? Seems like...

Dogman Dan, Are you a troll or something? All rock crawlers are solid axle. "Cantilevered in the middle"? It's called 4 link suspension. Try googling rock crawler. markz, the reason it could be good is because it puts the weight in a good spot - in the axle. Also you lose the weight of the engine, t...

Re: Quad /

Using gear motors can introduce issues with the built-in freewheel clutch since reverse is usually required in these applications. It's possible to tack-weld the clutch to defeat the free-wheel effect, but the shaft key on the planetary carrier takes a bit of a beating since it wasn't intended for ...

Re: Full Suspension Rock Bouncer Inspired Quad Build

Hey All,

Still working on the build. I am now planning on using two mxus 3000w v3 5t hub motors. My questions are now about electrical stuff. What controller(s) should I use? What battery voltage? Two batteries in parallel to increase voltage? If anyones got solutions and resources, I'm all ears.
