I tested a Chinese BLDC and am starting to "run" the numbers.
Noload: Io=1A, speed=1324rpm @ 48.6V (batt)
So, here's where I need my head checked - if tis motor is stalled then the current at 48V through the .043ohm motor will be 1116A. I base this on the equation V=E+IR (applied voltage=backemf+IR). Since at stall there is no backemf then V=IR.
I'm a bit stymied as the motor current at stall seems extremely high.
Also, maximun theoretical mechanical output is equal to V^2/(4R). In this case that equals 13395W. Again, this seems extremely high especially since the motor is rated for 500W at 48V.
Maybe I have this correct but need not be concerned since the current limit in my controller is what really governs the current and power of the motor.
Any thought are appreciated.
