As the question implies, How much current does a 24v 750w dc Motor uses
I have tried i=p/v = 750/24 = 31.25A
Which the result seems unreal to me as only 0.1A is capable to kill a human
Thankyou in advance, C. Shockley

Your equation is for the nominal operating point. If you want to have (750W - losses) mechanical output you need 750W as electrical input. It should be approximately right and the value is totally real.
The human analogy is not a good comparison here, because we are not a good power electric device like a motor, we are constructed for small signal electronics: transmitting control signals from the brain to the muscles.
Electrical input power of the motor on the name plate is actually for the full rated mechanical power output of the motor.
Thus a 750W motor run from 24 V will not demand 30Amp without mechanically coupled to anything significant.
There is no law to say mechanical power must only be stated in horsepowers. One horsepower is 746W and this means the motor is one HP motor.
This motor during free run (zero mechanical load) probably will demand a mere 5 Amps or even less.
