Motorcycle class Hub Motor

[alangsam1@me.com]

Hi Mark,

I like to know if I can use one of those hub motor for a motocross application (to replace An Agni 95 reinforced, Perm 132 or Lemco motor) with a 60 Mph top speed, I need to climb almost any hill like any ICE motorcycle does, the power pack solution for this motocross work at 79.4 Volt and 48 Amps (480 amps at 10C).

Thank's for reply and it's a great idea!

I have the same need for a motocross application. 45mph would be fine but to bikeraiders point needs to be able to climb and have the acceleration out of the berms and before the jumps to overcome the battery weight.

It would be a much simpler setup if someone would get this right. no chains and sprockets and lots more room for batteries. the common platforms are the
CR50 pit bike type, the YZ80, the YZ125 and a host of 250 types.

It is my intent to have Keywin build the 24 and 36 fet (150v) controllers with irfb4115 mosfets.
We will use 8 AWG for phase and bat wires. Six 470uf 200v Caps. Customized programming software.

I'll ask Mark to test the controllers on his dyno.

Then I will sell them.

Dirt bike build
YZ125 frame 603 motors

Hey Mark,

Look nice, i like the motor in the swing arm, this is the original swing arm with no mod ?, i'm impatient to see the rest of the built congratulation.

Good day!

Yes its the original swing arm lots more work to go, but you have to start somewhere

What is the rpm/volt? Looks like it belongs there!

 

[liveforphysics]

Outstanding choice in chassis. Off road handling doesn't get much better than that. It will be neat to see how it does with hubmotor power. Great work Mark!

The 603 is 7 RPM/VOLT

Thanks Luke

 

[markcycle]

Mark,

On the 603 can we apply more than 96 volt to get a higher top speed than 45 Mph? For a 55 Mph or 60 Mph top speed (like a 125 CC 2 stroke)?

Thank you, good day!

Sure can I rate the max volts at 144 you just have to maintain the 10KW cont. 30KW peak limits

I just purchased eight 6S 5A/H Lipo packs to configure a 100 volt starter pack. Along with chargers and other stuff to keep it safe

+1

Mark, you have to make a video of this in action, I think this could be a huge market for you. I think the 125's are the perfect size at this power. Awesome!!

So what is the ETA on testing the controllers

Mark

 

[Knuckles]

I just mailed Keywin a bunch of irfb4115 mosfets today.

Maybe 2 weeks for the first 24-fet unit ready for Markcycle Dyno "torture" testing ...

Specs:
150 Volt 100 Amp Controller
Standard: Hall, Throttle, Ebrake, and Ignition Wires/Connectors
8-AWG Braided Silver Phase and Bat wires (no connectors)
"Power and Phase Bus Braid" Soldered along Mosfet Power Traces
1 mOhm CONSTANTAN Shunt Wire (4-shunt)
Six 200v 470uf Rubycon Capacitors
Any Voltage Transistor mod
Regen/LVC (R-12) mod
English Software

And the expected cost of these controllers?
Mark, I will be relying HIGHLY on your input and suggestions when it comes time to wire up my Dual motor Trike.

I hear Ya and want your trike to run well as much as you do

Kelly has this product that should make it easy to configure dual motors

Hello and happy new year Mark,
I like the dual rear wheel motor arrangement as well.
Now when I get the leaning assembly completed I'll send you some photos. Hopefully in a month or two. It's below freezing in the garage so I am doing some "limited" engineering in the living room (when the wife's away).

Interesting ...
A Trike with TWO independent rear 602 motors w/
(OR TWO independent front 602 motors)
TWO independent 150v100a controllers w/
ONE throttle / ebrake and
ONE main (MEGA) battery pack

This thing would SCREAM Fast.

Curious how the two rear (or front) motors would behave
Maybe a really AMAZING feel on the road.
(Or maybe hard to control)

 

[johnhead@frontiernet.net]

Knuckles,
Not to worry. I'm in good hands with Mark. Two rear motors mounted on connected rear swing arms. As one goes up, the other goes down. Photos to follow in a month or so.... 96volts LIFO batteries. It will be heavy as I am fabricating the frame from steel but I'm hoping to get a top speed of at least 55mph out of her.

First test of the YZ125 build
This is with 36 volts of lead acid batteries I should be getting my Lipo batteries this week.

Now let's bump that up to ...

144V

 

[RoughRider]

its gonna be a ROCKET...@144V

 

[markcycle]

its gonna be a ROCKET...@144V

When I have a controller in my hand that can do 144 volts at over 100 amps, I'll buy the batteries to make it happen

by one from Kelly...500$

but i would by the bigger one...800$

I'm using a 120 volt 220 amp Kelly at the moment good for 136 volts. This should be OK to demo the motors capabilities

Very cool !!!...

i'm sure you mentioned this already, but i dug thru without success..

what gauge wire is used on the phase leads that exit the motor ?

6 AWG

 

[RoughRider]

that is not enought for 220Amp...is it?

 

[slayer]

i think the 220 amps comes from the battery pack to the controller. from the controller to the phases would be a different rating
