I have a 120100 brushless outrunner which is supposed to be rated at 25kw with a maximum 100volts. 50kv
I have had the motor running on 50v and the no load current is 5.5amp. When I run the motor on 75volts I am getting 10.5 amp no load current and the motor is heating up quite rapidly.
Does this indicate that 75v is to much for the motor and it is loosing its efficiency?
As the motor is for a bike application I could run a lower voltage and higher gear ration and let the motor pull more current. I am thinking this might improve efficiency? I don't think motor torque is an issue
