Well I ve been waiting long enough, ordered and received my gecko 540 with the 320 oz in motors this week.
First question, acording to the formula for voltage 32 x sq root of inductance = V
comes to 32 x sq rt 2.8 mh =45.1volts., is it close enough, or is it beter to somehow lower the 48 volt from the furnished power supply ?
There is a trim pot, but I havent tried it yet.
Second question: on gecko documentation it is stated that if your phase current is 3.5 or higher that no resistor is used.
that seem to contredict this...
