New build.

[103Alex1]

Too hot. After running in the enclosure even with the air feed it was too hot to touch (I was doing lost of standing starts whilst tuning the cruise control though). So it needs the air flow. I am pulling 1800 watts from it though.

OK ... that's a lot of watts if you run continuous !

Still, I enjoyed the project and I might revisit it later. I've got a carbon composite prototyping kit on it's way

£384 ? It better look bloody good for that

It's not just for that ;-) I'm making lots of bits for the Westfield - air box, wing mirrors covers, center console, arches etc.

Update:-

Kit now for sale and bike being returned to non-electric - it's served me well but I'm now retired and don't use it for commuting any more so it barely gets used. Next project is a crank drive full susser so keep an eye out for my next build thread

Latest project - just got the hub (Q100 rear cassette model), rim and spokes delivered and built it into a wheel this afternoon.

Currently waiting on an EM3EV 6fet programmable controller and a CA V2.3 computer.

Sorry to have to inform you, but there's a fair chance that it won't work with that controller. I seem to remember something from the distant past that it can't commutate fast enough. It's possible that they've improved since then, so there's a bit of room for optimism. Also, you have to play about with the phase and hall sequence. I don't believe that they go colour to colour, so keep the throttle low until it's running properly.

What speed is the motor?

 

[amigafan2003]

My last Q100 worked fine with the same controller from EM3EV - they are EB3 series based which are fine with high commutation motors.

Motor speed is 201rpm.

 

[Deleted member 4366]

Phew! That's made me feel a lot better. I look forward to seeing the rest of the build.

How do you all find the q100 (or 100h) compared to the SWX or BPM?

Considering options for next build.

 

[Deleted member 4366]

Its smoother lighter and quieter than a SWX, and probably a bit less torque. The BPM is a completely different motor. It's about three times the size, so it doesn't make sense to compare. The Q100 comes to life with 44v at 18 amps, which gives it 20% more power, torque and speed. There's lots of different Q100s. There's 201 rpm, 260 rpm, and 328 rpm. The Q100H has more power potential, but it's not a lot different at the same amps and volts. The Q100CST for cassette gears, which makes 6 different variants not counting the 24v ones. The SWX also comes in a lot of different speed ranges, which makes a big difference to their performance

Nearly done, just cabling to tidy up now.


Rear wheel installed - motor is barely bigger than the 11-26t cassette. Needed an extra washer in between the frame and the 11t cog.


Controls installed. Working from left to right - thumb throttle, cycle analyst V2.3, power switch and push button cruise controll and finally three speed switch. I want the CA more central, so I've ordered a mount that goes on the stem.



Pulled the brake switch out of a mechanical brake lever I ordered with the controller and fashioned a bracket out of some left over carbon fibre angle to get the brake switch working with the hydraulics - works a treat

Nice brake switches. I thought a man of your calibre would have been able to make a nice bracket for your CA. It only takes a Dremmel, a piece of 16g alloy and about 5 minutes:

Actually - I didn't follow through with the order so that exactly what I'm going to do! Thanks for the inspiration

All done (except relocationg the CA).:-



Quick test ride shows it topping out at 24mph no pedalling - bang on where I wanted it. Set three speed switch to give approx 13mph, 18mph and 24mph. Set the controller to pull 750watts to look after the motor (it's only tiny so no pulling 1kw+ on this one).

If you look closely you can the the controller painted black sitting just behind the seat tube on the rack supports - the controller "box" ontop of the rack actually houses all the conntectors - fed up with builds wondering what to do with them and wrapping them in tape to aid waterproofing and looking a mess (which makes diagnosing problems a mare and having to unwrap), so now all the connectors are shielded from the weather but easily accessible

Weighs a 15.5kg inc battery - not bad considering it's got a rack fitted as well

Wow 15.5kg with battery is very light. Whats the battery spec?

Where do you find this 16g alloy and how do you bend this alloy?

In the shed
With a hammer

"Rear wheel installed - motor is barely bigger than the 11-26t cassette. Needed an extra washer in between the frame and the 11t cog."

Just wondering why you needed the extra washer as I have same motor with 11t cog, and didn't use an extra washer ?

I normally need an extra washer with a DNP 7 or 8 speed free-wheel.

Cwah,

Rough cut it with a junior hack-saw or tin-snips, then finish it with your Dremmel. Bend in a small vice, or an adjustable spanner. If using an adjustable spanner, screw the jaws together until they grip the aluminium before bending.

thanks daveh. going to buy some of these aluminium sheets!

Where do you find this 16g alloy and how do you bend this alloy?

To make life easy you can buy one as shown below ready made in stainless steel for few pounds.

The expression "an engineer can do for a penny what any fool can do for a pound" amuses me.
By engineer, I assume that they have a workshop with a full armamentarium to perform their tasks which would cost a 'pretty penny' . Then there is the knowledge, skills and training to do the work.

Or are we talking about someone whose facilities are a limited range of tools, a kitchen worktop, a very tolerant partner and easy access to an A&E department.

 

[Deleted member 4366]

I wonder where they got the idea for that bracket from!
