Marko,
Looking at those figures, Io (the motor no-load current) seems to be a little high at 8.6A. It may be that this is related to the way the test was done, or perhaps, just an error.
Is this data from Hal or is it from the manufacturer? My experience with Chinese motors is that the specifications are often a bit garbled, possibly as a result of language problems. For example, one motor I bought had a stated Io of 3.6 amps, yet when I put it on the bench and tested it I found that it varied between 0.8A and 2A over the full voltage range.
The winding resistance, Rm, looks pretty good at 0.01 ohms though, the motor looks able to handle the current OK for short periods, although the I²R losses at 200 amps will be around 400 watts, so it will need some cooling. At a guess I'd suggest that the continuous power rating should be around half this (maybe around 140 amps), but that's still pretty good and a lot better than the nearest big, cheap outrunner.
For comparison, the HXT 80-100 130Kv, 6500 watt motor has an Io of 2A, an Rm of 0.032 ohms. At it's maximum voltage of 48V and max power of 6500 watts it will draw 135 amps and have I²R losses of over 580 watts, so far less efficient. There's no way the HXT motor will sustain 135 amps, either, my guess is that it'd get pretty warm if run at more than about 50 amps continuously. On bikes it's hard to draw currents of over 100 amps for long, though, at least on the road, so the average current is likely to be a lot lower, which is why people aren't burning these motors out. This big motor will be even better, as it looks like it should be able to run at maybe three times the continuous power of the HXT.
As soon as we hear from Hal I'll PM you, Marko.
