well but without using a torque meter ¿how would you measure motor´s
torque?

You can wind a string on the shaft and use it to lift a weight.

You can use F=mg and torque = F*r to find the torque from that.
(assuming steady state)

This is handy because you can also use it to measure speed at the same
time.
