Re: FREY eMTB with Bafang m600 is developing with your ideas!

Curious... what is the weight advantage of this model VS an AM1000 with the same capacity battery attached?

Re: Golden Motor, HPM 3kW non-hub w/air-cooling

As per liquid thermal control design... Ah yes of course :lol: Thanks T. What about covering the vent holes outside the fan requiring the flow to come from within creating vents on both case sides? Anyone know if the design allows an air path that would be proper for cooling? One could have an air f...

Re: Golden Motor, HPM 3kW non-hub w/air-cooling

Hey Thanks for that Luke! Curious as to their KW potential vs their rated size... within reasonable temps? And also... I've heard their liquid cooled models suffering from a poor design as well... Do you have any insight there or suggestions on how either design could be improved? I know you is the ...

Re: Golden Motor, HPM 3kW non-hub w/air-cooling

Great input here 8) My response from Golden about design comparison between this new 3KW vs their larger offerings: This 3KW model is new but the design is exactly same as our 5KW and 10KW model which have been for production in last 4 years. We just extended BLDC series to 3KW and 20KW models with ...

Re: Golden Motor, HPM 3kW non-hub w/air-cooling

One thing about GM's other motors is that they typically adjust the winding to give a similar loaded RPM on various voltages. You will find that with the 5-10kW motors, the efficiency and power output is best on higher voltages. The graphs for the slightly larger motor may tell you something about ...

Yes, there is a temerature sensor (KTY84) inside motor winding which is used for controller to detect overheat.

Thanks,

We will change windings for your specific needs. Basically we like to know the voltages, rated motor speed in RPM and rated power in watt...

Amazing as always Matt.
Wouldn't expect anything "less" from you :lol:
You always go ultra HP / light weight, but are you considering moto rims here?
Seems the final product (with the proposed battery pack) will be heftier than
your usual..?

I realize it's a shorter frame so you need to get out over it, but with a bit
shorter stem... the thing really has the "sport bike" look as well...
