Hi I can't identify the motor, but it looks 'interesting'. Deciding on running current / load is more difficult. That is what size of propeller will it drive?
There is a rule of thumb which seems to work fine. You will need a multimeter that reads up to 20 amps.
Apply the battery and put the meter in series and run the motor. Then using a pair of pliers grip the shaft and stop the motor and measure the current. Only stall the motor for the shortest time as it can disturb the magnetic field.
Divide the stall current by 5 i.e. take 20% and this will almost certainly be the most efficient running current for the motor.
If you look at the technical performance graphs of DC motors you can see how this seems to work out. (Often very nice 2nd. hand commercial motors are relatively cheap, and they last forever).
I have used it and motors seem to run cool and perform OK. Most mystery motors have come from a commercial source and as a tip 24volt motors powered by just 6 NiMh cells (7.2 volts) will turn a large propellor relatively slowly and suit a bulk carrier very well.
As a tip you can run an electric motor on just 3 volts from a modern esc which will have a bec for the receiver. Isolate the red wire from the esc and use a 4.8 volt battery directly into the receiver. Wire the 3 volt battery into the esc / motor circuit.
