If you have a permanent magnet motor, to which I apply some constant mechanical energy to its axis (I give it a torque and an angular speed so that it rotates and produces continuous current at its terminals) ... How can I measure the power electric that is delivering the generator? Is it possible to remove it with a Tester or Multimeter? If possible, can you give me the complete procedure for measuring power?

One can only add to the excellent response from the Colleague, Albert, that in the case of a "motorcito" as you say, the tension generated maxima will not vary much of the 3 volts c. c. for the normal flow conditions as a motor. Or is the speed of rotation as a generator should be only slightly higher than the one that you developed as a motor, so as to generate the tension design = 3 volt. Turning it to much increased speed will produce greater tension, but at the expense of decreasing the power that you will be able to deliver sobrecargandolo.

In theory yes, in practice it will be complicated, let me explain:
You have to first of all make the motor spin at a constant speed to generate the same power in such a way that it is possible to measure the voltage and amperage generated.
You put a resistance to close the circuit and thanks to the formula:
You can measure the voltage squaring and dividing it by the resistance that you put.
Keep in mind that the motorcito to generate a power output in function of the speed at which you rotate your axis.
