Motorcycle class Hub Motor

[markcycle]

Nice stuff! Maybe I missed it but how waterproof will the motor be? Submersible or just splash resistant?
Why do you have the torque arm pointing down then connecting at an angle instead of just parallel to the swing arm?
What voltage and current are you parallel charging the TS cells with?

The motor will only be splash resistant

The torque arm can be in any position that works for your application and of any shape so long as it is bolted to the axle as shown. Many motorcycle have a independent arm that picks up the torque arm for the rear brake. As I show it, the torque arm is connected to the drum brake support arm.

I parallel charged the TS cells at 3.8 volts

How hard do you think it would be to waterproof it for temporary submersion?

I parallel charged the TS cells at 3.8 volts

What current, and for how long?

Right now I don't think submersion is something I can work on, sorry.

I charged the 16 cells in parallel @ 35 amps until the current decayed to just about zero and it was apparent the current was not going to fall anymore.

I was thinking more along the lines of what an individual might need to do to make it waterproof. A bead of silicone on the mating surfaces and some rubber seals, or something more involved? Not a huge deal, just thinking of off road use, deep stream crossings, etc. I understand if you want get a regular version before building an underwater unit

Its doable rubber seals and dealing with the wires. I would need to make it a hole that the wires go through and not a slot so the seals have a good continuous shaft surface to seal against. So its a little different axle design and one worth pursuing in the future.

Building the first motorcycle with the MHM602 continues

 

[markcycle]

It's been a long wait but the moment has finally happened

I present to you MHM602 motor

 

[JRP3]

Nice work!

 

[Jozzer]

Good work Markcycle, get it int here and give us the feedback

 

[michaelplogue]

SWEET!

I present to you MHM602 motor

Very nice looking, elegant design. Good job, I can't wait to hear how it performs!

Oh.. sorry Mark

For revelating it few times sooner on the forum I didn't know you wanted to keep that until today

Doc

Hey doc

This thread is all about the Motorcycle hub motor, so no problem. now the question is do you want to race 8)

I'm glad you started a thread that showed my youtube videos. Things get lost in a long thread like this one.

Hey doc

Mark

.. great idea...!

But..
Levittown and Quebec city .. not so close!

let's do the 0-100m on a video and lets compare us with video?!

Ooooh, now this could be cool. Do it! Do it!

Sure but first I have to finish the bike and I think Doc has to wait for the snow to clear and get his Wye/Delta setup going

Nice vid mark, you have me drooling for more. You should post that video here too!

I'll be really interested to see how the heat dispersion works out too.

PS - I just realized where you are - I'm a Philly transplant myself

Thanks video seem a lot harder to do than pictures and take more time but can be more informative.
I will definitely do more videos
I did post the Video here, with long threads things sure do get lost. I think I may start a new thread when I begin test the Electric Lifan bike

I live in Levittown New York, two towns same name different states.


With 72 (24s2p) volt and the controller doing peaks of 160 amps averaging 85WH/Mile during a 30 minute ride, I couldn't get the motor hot. Maybe 10 degree rise above ambient. If you look through the Motorcycle Class Hubmotor thread, I show all the data for several rides. Data was taken using a CA serial data out logged to a tablet PC.

The inability to get the motor hot is one of the reasons I'm going to 96 volts and 200 amp controller with the next build. I need to know how much power the motor can deliver verses temperature rise. I'm hoping to be able to do this without going to a Dyno but I will if I have to.

What speeds were you hitting with that config?

45 MPH I'll re post the data it's back on page 4 or so
The time base is .2 seconds

A quick dry fit of the MHM-602 in my test motorcycle. I haven't fitted the torque arm yet. Just got the wheel, put the tire on and had to see how it fit and looked in the frame of the Lifan

You sir have made me want to throw my puny little ebike in the shed and step up to the plate with one of these bad boys!!!
I am jealous and wish I had some dough right now. Count me in next year boys!

I see there is an arrow on the hub. Is it possible to run the wheel backwards after flipping it around?

What is on the left side of the hub? Can a sprocket be attached to the left side?

Yes it is possible to run the wheel backwards either by flipping it around or through the controller.

I designed the hub to take a sprocket on the left side so I could develop a parallel hybrid version of the hub motor. There are mounting holes on the left side for a sprocket.

She sure is pretty if I must say so myself. I just love seeing my designs going from paper to product, even after 30 years of doing it, it never gets old.
