Hi basically I have an application where I need an esc for a brushless dc motor that uses standard rc pwm input.
The motor im controlling was going to have a maximum supply voltage of 25 volts. I would be ok with dropping the max voltage at the power supply down to 24 volts which is the rated maximum for theDFRobot 40A.
Normally in electronic design you want at least 15% overhead capacity for reliability.
But in this case where it will only be turning a small plastic propeller, probably drawing a few amps maximum current on a 40amp rated esc, dov you think i’ll be OK running the DFRobot 40A with maximum supply voltage of like 23.8 or 24 volts? (It’s rated voltage is 24 volts max.)
I just dont want to set the voltage of the power supply to like 23.8 volts, then have the ESC die after a few uses because the 23.8volts input is right near the 24 volt rated maximum. But again its a low current application, much less than 40amps, so the power should be much lower than the rated max. Just that there wont me much margin of safety between the max voltage specification and the max voltage of operation at full throttle.
I assume it will be OK since the violtage will be at max spec but the power should be a lot less. What do you think? Also, how soon can I recieve the DFRobot 40A if I order it today???
Thanks
