Re: The Beast Mid Drive. 3 Beta Testers Wanted!

Does Australia count as Oceania? Some people say it does and some say it doesn't... I could cover off on those criteria- I was thinking about buying a GNG for my next dual susp build as we have some good off road mountain biking here. I could also test it on my daily 25km commute to work (Norco Shor...

Re: Anyone here have a Volt?

I drove a Volt here in Perth Australia and loved it! Nice inside, drive really well and I would be tempted... but down here they cost $59999 PLUS on road costs (another ?$4-5k). So a very very expensive option. No rebates here!

Damn shame.

If it makes for a neater wire run to the hub I don't see a problem drilling there. But do you really want to drill it? Looks so purdy in that fresh white paint... :P

Yup, been there done that! There might be a few useful bits in the repair thread in my sig?

Re: Cromotor v3 Temp Probe

That looks like a sort of "knead-it" type epoxy putty. It must be getting hot to disintegrate- this is from the website: Heat resistant to 120°C continuously or 140°C intermittently. Those temp sensors are on the stator not the windings so 120 on the stator is HOT!!! Personally I'd try to keep it be...

Re: Something is moving in the hub but the wheel aint.

Yup ,having seen that video I'd agree. I'd be checking the hall sensors first (small plug with red, black, yellow, blue & green wires to it normally). Wiggle it, unplug it and check that all the connections are good. If not that, then test the three phase wire connections. If it's not any of those t...

Re: Too much air cooling is bad

Rather than saying 'too much air cooling is bad', perhaps it would be better to say, "Removing load bearing material from an object can have negative consequences." To be honest, it's a surprise you caught it when you did and that this didn't end in a far more interesting way. Yeah, I did take some...

Some good points there. I agree about never cutting reinforcing ribs! That chinese cheese metal is weak enough to start with.

Too much air cooling is bad

A cautionary tale. .. I bought a second hand 9C rear hub motor which had been drilled for air cooling. I wasn't totally happy about the location of the holes. ... especially a number of large ones near the axle on the freewheel side. It actually lasted quite well- a few thousand kilometers- but I li...

Re: Something is moving in the hub but the wheel aint.

1. Depends on the type of motor. Direct drive- could be magnets have come loose and are rotating. Easy fix- take motor apart, remove magnets and reinsert with a good two part glue. Geared- could be stripped gears or broken clutch 2. It will never be maintenance free! All depends on how lumpy the roa...

Wow you can really see where those magnets were moving around the hub shell! Obviously all the epoxy failed- must be pretty low temp rated! If you had massively overheated your motor, the windings would be dark brown and the strings around the windings burnt, which they aren't. Just an idea- try sli...

Re: Axle partially spun in the dropout, could it cause this

Don't stress too much, the axle hasn't spun in the stator. (Dammit Tench just beat me to it! :) ) If it had, the phase and hall wires would be broken and twisted around. The wiring on the halls looks completely normal by the way. The slot you can see on the axle looks like the wire slot- if you have...

The ss411a is the hall sensor of choice for most of our motors. Every time mine have failed I've replaced them with these- sometimes I couldn't even see what the old ones were.

This approach works well. Round holes near axles and kinda slot type holes near the periphery

My 9C at 2kw never gets above 70C (on a 40C+ day).

Re: Cromotor v2 RUB, UPDATED 7/16 MAGNETS UNGLUED! HELP!!

It could be magnets spinning... or just pulling away from the iron backing and hitting the stator. The magnets stick well to the hub/can/rotor or whatever you want to call it because it is a steel ring (this enhances the overall effect of the motor rather than having them in an aluminium can). They ...
