    Homemade 2kW brushless motor EV now with fairing & no solar

    Hi Guys, I just realised how long it has been since I visited this forum, nearlly 2 years. I never had any issues running different F&P motor winding types, controller types etc with any F&P standard hall sensor board, maybe the older hall sensor boards were set up differently. I had the...

    DELTA only 9C type Electric Pitbike 20" BMX Wheel

    Yes lots of fun and sadly dad uses it more than the kids. Delta is much better for this Pitbike, as in star it might have a bit more torque from start but as it only goes about 25 to 30kph in star the current draw drops off very quickly and so does the power. In Delta it keeps on drawing 55Amps...

    ELECTRIC TRANSMISSION DELTA /WYE and SERIE/PAPALLEL stator

    Hi Guys, After already posting a thread about my Epitbike conversion with DELTA only, I then found this thread and thought someone might like my picture and video. 9C type motor with a no name 48V / 12Fet controller beefed up from 26A to 55A and with no issues, even in delta with continous high...

    DELTA only 9C type Electric Pitbike 20" BMX Wheel

    Here's my latest project, a 1000W star wound brushless ebike motor in a 20" BMX wheel with a standard 12fet controller beefed up to 55Amps (about 2kw) and the motor re-wired in DELTA only, gives great torque and goes about 50 to 60kph. Picture shows battery bag up high, but now it has a lower...

    Fisher and Paykel motors

    Hi Guys, Heres the PM I sent to enoob. Yes that sounds like the newer generation motor at .6mm. How may coils?? You will find that it is designed for high voltage and very low amps at about 1.5A if used as a alternator. I don't think it will go very well as is but maybe worth a try but it...

    Fisher and Paykel motors

    Yes it is all going very well and have given it a few good runs with the fairing. The cheap crappy front wheelchair wheels are not handling the load well and I have been given some good steel wheel chair wheels to use but the hub if different. Controller gets bloody hot at 49amps but I often am...

    Fisher and Paykel motors

    I have no real figures yet for efficiency etc, but these will come soon. I can say that the 12fet infineon controller at 48V / 48Amps really seems to work well with this motor and seems to be putting out amazing power. Did you check the youtube link as it shows the potential of these motors...

    Fisher and Paykel motors

    Excellent, someone else has also played with these F&P for EV motors. That multi strand rewinding is what I have wanted to do also, would love to hear how it goes, and a great job on rewinding. I highly recommend going for the neo magnet conversion as it feels like 4 times the magnetic...

    Fisher and Paykel motors

    Hi All, just a few notes. The stators are about 5.3kg. The shaft is easily removed or cut down. The complete motor in the picture below weighs about 8kg with some excess plastic housing (this is the quick method of getting them out of the tubs, a hammer) I then machine the bearing housing...

    Fisher and Paykel motors

    Just waiting up for santa to come so I can go to bed, kids. As for shipping, if ecoinnovation in NZ can ship 3 complete motors to US for $250 then the cheaper quote sounds correct. You always end up with 6 wires on a 3 phase motor or alternator, as each phase needs to have 2 wires (start and...

    Fisher and Paykel motors

    Hi Guys, That's the way Kim, I also had a repairer who would drop off all his F&P tubs complete with motórs in my front yard, they are literally everywhere overhere. I moved and lost contact sadly. So as kim mentioned, I'm sure you could work out a slow cheap shipping method somehow if Kim...

    Fisher and Paykel motors

    I have not heard of anyone rewinding them but just reconfiguring them as they are in series from factory and have a high voltage low amp arrangement. I do have a stripped down stator so i could rewire it and now I might use maybe 8 strands of small wire and wind about say 10 turns and work out...

    Fisher and Paykel motors

    The wearing is due to the ends of the bolts touching the rotor as I have something left out, washer. That steel idea sounds ok, but i would really like to start with a complete new rotor,will see how things go. It runs fine for now so will just let it go and keep pumping more amps into it until...

    Solarcar power slide "now with fairing" but no solar, justEV

    Thanks Kim, Will try it next time when posting a youtube link. See link to the fisher&paykel thread, i have attched some close up pics of the shaft etc. http://endless-sphere.com/forums/viewtopic.php?f=2&t=942&start=15 F&P Matt

    Fisher and Paykel motors

    Hi Guys, Heres some close up pics of the F&P stator and shaft spline and magnet rotor spline. If anyone has an idea of how we could make up a aluminium magnet rotor with a steel magnet keeper inside at about 3mm or so, that would be great as we can get these stators no problem and Im sure we...

    Solarcar power slide "now with fairing" but no solar, justEV

    See youtube link of the trike spinning the rear wheel in reverse and then forwards on our bituman driveway with a nobby BMX tyre. Will soon learn to attach a video correctly. Still has more go in revesre and will be adjusting that hall location any day now, and most likely set it up with...

    Fisher and Paykel motors

    Yes I feel the same. The first thing to let go would be the plastic magnet rotor spline though. I have many different F&P motors around and can afford to sacrafice a couple for science. I will be getting a 18Fet controller soon which should beef it up a bit especialy with the IRFB4110 fets, but...

    That makes me feel better about the hollow hubs. Matt

    Fisher and Paykel motors

    I think LG and F&P make these motors and others are following. There are plenty here laying around in OZ and NZ but shipping may not make it cost effective. F&P had bad electronics but the motor does not fail, this is why there are so many laying around, some only a few years old. My newest...

    Solarcar power slide "now with fairing" but no solar, justEV

    Thanks Kim and Amberwolf, Amberwolf, yes please copy my front end design, it works a treat and costs nothing and is strong along with being able to last a long time. Yes they are el-cheapo $20 new wheel chair wheels and the hollow axle version with a small amount of thread on the outside. I...

    Fisher and Paykel motors

    Hi All, Yes have been experimenting with the F&P washing machine motors, first as wind turbines and then even using a 1mm motor in parallel as a welder at about 2500rpm, worked great though a big rectifier. They can be re-configured in many different ways and there are 3 different motors all...

    Solarcar power slide "now with fairing" but no solar, justEV

    Thanks for that info. The controller I am using is the smart variety that can sense 60 or 120deg. Infineon 12fet, 45A running at 48V, voltage & Amps can be higher. I think mine is 60deg. Yes should start a new thread on this F&P motor as i feel it can be a good DIY brushless type of project...

    Solarcar power slide "now with fairing" but no solar, justEV

    Thank's Aussiejester, will have to send out some PM to peolpe to see what tyey thing about the hall sensor location question. Still yet to swap the phase wires, and try it in reverse mode which will be forwards with the wires wiotyched and will see whatb hepens hten. i definatley has much more...

    Homemade 2kW brushless motor EV now with fairing & no solar

    Now has a Corflute fairing that cost only $30 all up. Will be adding colour soon and a perpex roof, see first pic has a white line to show basic shape of roof. Should go though the wind a bit better now I hope. F&P Matt

    Solarcar power slide "now with fairing" but no solar, justEV

    Hi Guys, Need to know what anyones thoughts are regarding the positioning of my current hall sensors. I mentioned it does have more torque in reverse and much less speed and still good torque in forwards but much faster. Maybe I need somwhere in between like stabndard BLDC motors??? Will be...
