I figured 100m (328 feet) is a decent equivalent to 1/8 or 1/4 mile testing for automobiles, so I customized my Dragy runs to capture: 0-30mph, 0-40mph and 100m times. Just for reference I am 205lbs and testing a stock Bomber will do high 4 to low 5 second 0-30 mph (depending on SOC and rider weight). The best time on the bike pictured below was achieved with with my highest controller setting tried that day of 150 battery amps and 300 phase amps, with flux weakening and boost mode turned off.Bomber.jpg
Those times seem good, but I don't understand anything else. 300 phase amps, what's that?
How many amps max did your ca show?
Every electric setup has DC amps, that is what controller sucks from the battery And then what it puts to the motor is called Phase amps. (motor has three phases, green, yellow and blue cable)
More phase amps means more power to motor and thus better acceleration. When you program a controller you always setup your DC and phase amps. if we are talking about stock surron it has 90A DC and 450 phase A.
Wow, I didn't know the Phase to DC amp ratio was north of 4:1. but that makes sense as the phase wires on the SurRon are HUGE.
That is a bunch especially considering they're only 60v. I assume that means 100a per leg? Three legs = 300a.
Between the controller and the battery there can be 90a?
