This thread is to sort all MEASURED caracteristic of the X5 motors
after all.. it's the most powerfull hub motor we can get for bicycle...!
Every time i dissassemble one i carefully measure and note everything about them that is under the cover.
( all with calibrated fluke equipment)
-number of pole:12
-number of magnets: 24
5302: 10x2T
--Kv: 18.2
--number of strands: 10
--size of each strands: AWG 20 ( 0.032"dia)
--All strands = to one 10 AWG
--inductance bewteen two phase wire: 79uH with my meterman XR37 and 109uH(retested with calibrated Agilent LCR meter) 5 jan 2014
--DC resistance between two phase wire: 0.045ohm (direct to winding)
5303: 8x3T
