New Engine Design LOWRACER HYBRID - high torque BLDC MOTOR

For this special moment I've worked a half year!
I wanna have a maximum of performance for a
minimum of space! Now it works, I can handle
a high torque from low rpm to high rpm!
And that of course without a gearbox or a speed
hub. The speed will be changed by the
frequency of the controller. I shift into another
speed with a "TipTronic", that's only 2 button,
one accelerate and one decelerate!

Technical test data:
TIRE - 20" SCHWALBE MARATHON
LOADING ON TIRE - 48Kg
SYSTEM VOLTAGE - 37V/42V LiPO / 150Farad CAPs
MAX AMP LOAD - 70 AMPERE
CAPACITOR BLOCK - 19x22000uF
TUNNEL HEAT SINK - 0.4K/W
MOTOR-CONTROLLER - COMPLETE CONVERSION
MOTOR - AIR COOLED 500W BLDC HUB MOTOR

Für diesen besonderen Moment habe ich ein halbes Jahr gearbeitet! Ich möchte höchste Leistungsfähigkeit auf engstem Raum. Jetzt funktionierts, ich kann also grosses Drehmoment von langsam bis schnell handhaben!
Und das natürlich ohne ein Getriebe oder eine Nabengangschaltung. Die Geschwindigkeit wird durch die Kontroller-Frequenz geändert. Ich schalte in einen anderen Gang mit einer "TipTronic", also nur 2 Knöpfe, einer beschleunigt und einer verlangsamt!

TECHNISCHE TEST DATEN:
REIFEN - 20" SCHWALBE MARATHON
REIFENBELASTUNG - 48Kg
SYSTEM SPANNUNG - 37V/42V LiPO / 150Farad CAPs
MAX AMP BELASTUNG - 70 AMPERE
KONDENSTOR BLOCK - 19x22000uF
TUNNEL-KÜHLKÖRPER - 0.4K/W
MOTOR-KONTROLLER - KOMPLETTER UMBAU
MOTOR - LUFTGEKÜHLTER 500W BÜRSTENLOSER GLEICHSTROM NABEN-MOTOR


Thanks for watching!

like that back ground music!

@3089280288 Thanks, selfmade! I sent you another video with the full length music...

[MPaulHolmes]

You are the man! I've got a crappy brushed hub motor for my bike. I need something like what you have there. Nice job. awesome.

[ChrisLuxembourg]

@MPaulHolmes

Thanks! ...BUT, that's only a pimped out direct drive motor made in china...

[BungaEBiker]

WOW that's a monster controller man. You built your own controller. That's impressive all by itself. The rest is just out there, this is frigging amazing.

[ChrisLuxembourg]

Monster controller?- No, it's not big! It's based on a "NoName" controller made in china, and I've converted it a little bit... So it's maybe more around the controller, to dissipate all the heat from the MOSFETs and the coils, also stabilize the voltage&amps...

The problem was that the bldc hub motor don't have a speed hub, so the battery and the controller must generate the electric power for the torque and speed!
