36V is the max voltage obviously. With know voltage and wattage you can determine that the current is about 14amps but that's it's RATED power not what it will do during a stall, the DC resistance of the coil will determine the stall current which is a value you haven't listed. I'm not sure how you would determine what the coil resistance of a BLDC motor is, aside from opening it up and using a meter. Depending on how you control the motor though and how it senses you need to keep in mind that if a sudden load is applied which causes the driving/applied voltage to be out of phase you could get much higher voltages, worst case scenario is double the voltage, and you'll want to derate from that value.
Those are just theoretical considerations, someone else here probably has more practical advice to give (at least I hope so)
