Re: Definitive Tests on the Heating and Cooling of Hub Motors

The green compound the copper is in cased in looks like it, would no doubt, be detrimental to the over all cooling process, claims of 6k continuous, has anyone got one of these can report findings?

Re: Definitive Tests on the Heating and Cooling of Hub Motors

has anyone done a system where you shoot water at your hub with a water pump, water on the hub is very effective at cooling the motor, I find that the hub motor with fins and ff work well with no Re Gen but as soon as that Re Gen kicks in the hub becomes a grill pan, although it does stop the motor ...

Yes one of these would be boss, now how do i get the money. Do you think they are going to be a better version of this somewhere down the line, because with 80-100 volts and a slightly wider frame for moto tyres this could replace dirt bikes?

Re: Advanced ADAPTTO controllers and compatible products

I think the problem with adaptto was with the mosfet number they only used 18, sabvoton uses 36 for the same power. mosfet number is related to the wave signal to the motor, it seems to me that the more mosfet you pack the higher the wave function (complexity of the wave, or purity of sine wave shap...

Re: Adaptto Mini-E/Max-E Owner's Thread

only problem is if you have a cromotor with 60 degree hall sensors sabvoton doesn't work with it, so you are stuck with not to many options, apparently the kelly controller is really good with the cromotor, any one know other controllers that work well with a 60 degree hub motor?

Re: Advanced ADAPTTO controllers and compatible products

Man this adaptto is sort of hit and miss, some people it works others don't, I really hope they increase the success rate some how with the next iteration because having an ebike you setup as an adaptto machine and having the controller not work is a real pain in the ass
