Thank you for your message, may i know your name?
For the weight, it should be similar with 205, i will measure tomorrow.
So you are using our 205 1000w spoke hub motor? Which is your wheel rim size?
Well Judy, hello again. My name is Jean-Paul..... The rim size is 24.25" OD.
I seem to have damage my 6 month old 35H V1 205. It only lasted 650 miles.
However, I have been running ( the 1000w V1) on (5x) the recommended current ... and (2x) the recommended voltages.. for (8x) the recommended power... Do you think this had any forbearing on the damage? Perhaps.
I look for another Qs that will fit my application. I have a very important question.. do you think the damage is from the stator, or the halls signal?
The question is :
Does Qs use many grades of stator varnish, insulation for the windings, for a rated "48v" vs. a rated "72v"? Will running a "QS 205 V1 48v" motor at "90v" hurt ( damage) the winding? Is this why my motor failed? Must I buy a "72v" hub for use of HV?
Question 1: Do you use different grades of stator protection for increased voltages??
Question 2: Also, is there any known problem with running square wave control on this QS205 23pole motor? I have read of blown square wave controllers.
I currently look for a hub motor to supply with 134v. I need to know if the 72v version will suffice... or be damaged in very few miles? My contin power will be in the range of 8000w... and the peaks for M/Sec/Sec may be quite a bit higher. Top loaded speed goal is 55mph. I will use the same 19" rim for 24.25" OD rolling dia. Or perhaps a touch smaller, like 17".
I would buy today, but I only have no money and a broken hub.
Thankyou for the time.
