First Hello to all Forum User this is my first Post .
My Name is Martin i´m from Austria .
I learn English in the Ground-School (18years ago ) an never really use it, so sorry for my Bad English
Early 2014 i watched a Movie about Elctric Vehicles and im getting interesed in Electric Mobility and the History of Electric Bikes like this (THE DOUGLAS PIDCOCK 1922/1942 ELECTRIC EV MOTORCYCLE) .
I read much about Controllers-Basic´s ,BLDC -Motors ,Brushed -Type,Accu(BMS),Neodym Magnetics et cetera .
The most knowledge i had from study Forum-Pages like this(EndlessSpähre) and a german Webside whos called Pedellec Forum .
In early 2015 i began to "transform" my old small D.I.Y Costum Moped into Electric drive, meantime 2016 i made some improvements .
Orignally it was a APRILLIA RED ROSE 50cc also Called... Aprillia Classic
Now i called it the "Transformator" :lol:
For my Project i order a HPM3000 48volt 80amps Motor from GM and two 52volt 20amps Lifepo4 (Factoryname:Wolong) (Delivery Time was about 60 days in realtime!?)
Meanwhile i work with a smaller Test Motor .
The first Prototype (test phase) works with a cheap 1600Watt(Input2000W) BLDC and a EVO- OKW16P-4 Controller .
I only take this Motor and Controller for testing the self made construction of gearboxadapter and sprocket
Later i will use the little Motor and Controller for a small "Children Toy Quad"
For the first ride i drive the Bike with 4* 20A 12Volt Lead Acid Battery´s .
They were mount on the rear Fender in the Saddlbags on a Special-Construction .
It look´s like Saddlebag´s but in real they were substantially build with Steal .(inside!)
Bodyshop-work
Bevor the first ride i do not expectet much Power becouse of the little Motor .
But the first testride was real impressed.
With the first gear i belive I can pull a little Tractor or drive a gradient of 35 per cent witout problems .
In the fifth an last gear the Bike get max Speed 35 Km .
This tiny Motor amaze me so little so huge Power .
Before the Bigger Motor arrivied i rebuild (tunnning) the Evo Controller .
I cut of the 12 Fet´s and wired the new Fets directly.
From the tuned Shunt the Minus(-) is wired directly to the Fet .... and the Plus(+) is also direct Wired so there is no real Power on the Platine so the thin Soldering of the Platine cant get even warm or melt down and shot the Circuit.
i know it looks agly but it work
Usually if a Controller was tunnend we use more Fets . I take less Mosfet i take six Fet but bigger one´s (TO-264 I=550A ,RDS 1,6mOhm(IXTK550N055T2) )
The tuned Controller works perfect i can touch the Mosfet under full load and the even get little warmish .
Also the RPM goes up to 4750 rpm before it was around 4150rpm .The Bikespeed goes up to !!
Transform a Cheap Controller to a Homebuild Power Controller ( i love to perform handicraft work)
The Motor-heat actually is not grow up .
After the GM Motor and the Battery arrived i make some enhancements .
(to learn from mistakes " improvements i made in 2016")
*) I took the Battery from rear(swing arm) to the middle of the Bike, because the Weight of the Battery was not good for Handling this Bike !
*) The Master Switch is now also in the Middle !
*) There is no more wire on moveable Parts like Swingarm !
*) I mount a fuse Box (fuse for Battery-BMS,fuse for DC-DC Converter,)
*) I change the DC-DC Konverter to a stronger one! now the the ligths not goes low, when switch the Horn or Brakelight .
*) I also mount a Voltmeter (on Tank) and a Amperemeter for Charching so i always see whats going on .
*) Now Every Battery had her own Fuse !
*) I change the front and rear Sprocket from 13/46 to 15/44(gearbox/tire) .
*) I change the sprocket from BLDC to Gearbox too ! Before it was 11/14 now 14/11
This Pictures show the work for the bigger Motor
Cuting the Alu with the saw was better and easier "power cut will work too " i prefers the saw !
it´s fit so now brush grinding work get´s startet .
so i take the parts together ....
so the Cover is ready to mount
so that´s the place were the controller live
the fuse and dc-dc converter -Box with Amperemeter to watching recharge the lifepo .
so the finished mount hpm3000b
so the vintage voltmeter on the ex-fuel tank
Some small things to do but the most Work is done .
My dream were those Batterys-Pack with SAMSUNG INR18650 29E cell -( http://www.elektromoped.at/product_...ung-xxs-lithium-batterie---li-ion-2064wh.html ) they had the same dimensions and would fit perfectly but these tooo expensive may in future is getting cheaper !??
Meanwhile the LiFePo4 works great to ! Much better then the heavy lead Acid Batterys .
Pictures of the real finished Bike coming soon .
yours faithfully
Martin
