P94 Dual Esc And Mixer and motor choice
Hi all good questions! Don't worry about the tiny difference in voltage for battery power. I have a few 380's and they are quite powerful I think around 40 Watts.
The 385 is a similar size but has a 5 pole motor, is less than half this.
This makes it a different motor and has a wider voltage range. The main thing with electric motors is make to sure they run as cool as possible. The hot spots are around the commutator and brushes. You could use a coiled tube with a water feed to keep the motor cool but not to worry in this case as the 385 is a lowish power motor.
You can run the motor at any lower voltage but I would not go to more than 20% higher. than the rated max voltage. Keep the revs up and the motor will run fine.
I was running 2 off 600 motors rated at 9.6 volts on 12 volts with small props so the revs were high. The battery got hot but the motors were just warm, and I watercooled the single Electronize ESC which was running at max capacity of 15 amps and that was stone cold. With this esc there was a voltage drop across the unit so voltage on motors was not 12 volts.
If you have a multimeter you could check the voltage on the motor and you will see it is a bit less than the battery voltage.
For the smaller motors that run at up to 8 volts and 3 or 4 amps there are some impossibly small esc's that do not get warm and available from China / fleebay.
I use them a lot and they used to be about £2.50 each but if you search you should find them at £5 or so, some rated at 20 amps but I do not believe this! They are however excellent only sight drawback is the battery connectors which are the old 2 wire battery conectors used on RC receivers for battery connectors, but ready made connectors are very cheap to suit.
These used with a mixer will suit you, I have one I bought waiting for me on my return from the land of Oz
